This study evaluated the potential of horseradish (Armoracia rusticana) oil (ARO) and eight isothiocyanates (Pr ITC [ProITC], iso-Pr ITC [IsoproITC], Bu ITC [n-BuITC], 3-butenyl ITC [3-BeITC], Ph ITC [PhITC], benzyl ITC [BzITC], 2-phenylethyl ITC [PhEITC], and allyl ITC [AITC]) as preservatives and antifungal agents for postharvest tomato disease control. Results showed that ARO and eight ITCs demonstrated antifungal activities against Botrytis cinerea, Alternaria alternata, Rhizopus stolonifer, and Geotrichum candidum, which can cause the decay of mature green tomato during storage. Allyl-ITC (AITC) had the lowest EC50 values of mycelia growth suppression, with 0.18, 0.44, 0.29, and 0.43μg/mL air for B. cinerea, A. alternata, R. stolonifer, and G. candidum, resp. ARO, 2-PhEITC, BzITC, and AITC exhibited better efficacy as preservatives of mature green tomato than other ITCs on the basis of some parameters, such as low decay rate, slow reduction in weight loss, slight change in hardness, slow decrease in acidity, and total soluble solid content of treated tomatoes. GC-MS revealed that 2-PhEITC (77.78%) and AITC (15.87%) were the major components of ARO. These results can be used as a basis to develop preservative products composed of ITCs. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Application In Synthesis of Isopropylisothiocyanate).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Isopropylisothiocyanate

Comparative evaluation of physical properties and volatiles profile of cabbages subjected to hot air and freeze drying was written by Rajkumar, Gomathi;Shanmugam, Saravanan;Galvao, Mercia de Sousa;Dutra Sandes, Rafael Donizete;Leite Neta, Maria Terezinha Santos;Narain, Narendra;Mujumdar, Arun Sadashiv. And the article was included in LWT–Food Science and Technology in 2017.Electric Literature of C4H7NS The following contents are mentioned in the article:

The aim of the present study was to evaluate the phys. parameters, volatiles profile and sensory quality of the cabbage pieces subjected to hot air drying and freeze drying processes. Phys. properties such as water activity, shrinkage, hardness, springiness, cohesiveness, chewiness, rehydration ratio and color measurements were measured using standard procedures while the volatile compounds were determined by the SPME-GC-MS method. The results showed that convective drying of cabbages lead to major adverse changes in phys. and volatile compounds characteristics. Hot air and freeze drying of cabbages display different volatiles profile containing aldehydes, alcs., terpenes, ketones and furans. Better retention of character impact cabbage green and pungent aroma compounds viz. allyl isothiocyanate, di-Me sulfide, di-Me disulfide, 1-octen-3-ol and (Z)-2-penten-1-ol was found in freeze dried cabbage. The presence of 3-(methylthio)-Pr isothiocyanate, Me benzene isothiocyante and Ph Et isothiocyanate is reported here for the first time in fresh cabbages. The flavor components of fresh cabbage were largely retained in the freeze dried product. Freeze drying also leads to pos. sensory effects and better overall acceptability by consumers compared to the hot air dried product. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Electric Literature of C4H7NS).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Investigation of flavor-forming starter Lactococcus lactis subsp. lactis LDTM6802 and Lactococcus lactis subsp. cremorisLDTM6803 in miniature Gouda-type cheeses was written by Lee, Hye Won;Kim, In Seon;Kil, Bum Ju;Seo, Eunsol;Park, Hyunjoon;Ham, Jun-Sang;Choi, Yun-Jaie;Huh, Chul Sung. And the article was included in Journal of Microbiology and Biotechnology in 2020.Recommanded Product: Isopropylisothiocyanate The following contents are mentioned in the article:

Lactic acid bacteria (LAB) play an important role in dairy fermentations, notably as cheese starter cultures. During the cheese production and ripening period, various enzymes from milk, rennet, starter cultures, and non-starter LABs are involved in flavor formation pathways, including glycolysis, proteolysis, and lipolysis. Among these three pathways, starter LABs are particularly related to amino acid degradation, presumably as the origins of major flavor compounds Therefore, we used several enzymes as major criteria for the selection of starter bacteria with flavor-forming ability. Lactococcus lactis subsp. lactis LDTM6802 and Lactococcus lactis subsp. cremoris LDTM6803, isolated from Korean raw milk and cucumber kimchi, were confirmed by using multiplex PCR and characterized as starter bacteria. The combinations of starter bacteria were validated in a miniature Gouda-type cheese model. The flavor compounds of the tested miniature cheeses were analyzed and profiled by using an electronic nose. Compared to com. industrial cheese starters, selected starter bacteria showed lower pH, and more variety in their flavor profile. These results demonstrated that LDTM6802 and LDTM6803 as starter bacteria have potent starter properties with a characteristic flavor-forming ability in cheese. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Recommanded Product: Isopropylisothiocyanate).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: Isopropylisothiocyanate

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Computed Properties of C4H7NS

Synthesis, characterization and investigation of the antioxidant activity of some 1,2,4-benzothiadiazine-1,1-dioxides bearing sulfonylthiourea moieties was written by Harrouche, Kamel;Lahouel, Asma;Belghobsi, Mebrouk;Pirotte, Bernard;Khelili, Smail. And the article was included in Canadian Journal of Chemistry in 2019.Application In Synthesis of Isopropylisothiocyanate The following contents are mentioned in the article:

A series of 1,2,4-benzothiadiazine-1,1-dioxides bearing sulfonylthiourea moiety I [R¹ = H, Me, Ph, Bn, 4-MeOC₆H₄; R² = Me, i-Pr, cyclohexyl, Ph] were synthesized, characterized and screened for their antioxidant activity, using six antioxidant anal. assays comparatively to reference compounds, ascorbic acid and quercetin. The results indicated that several compounds I demonstrated strong antioxidant activity in DPPH, ABTS, H₂O₂ and lipid peroxidation assays where some of them were either as active as or more active than reference compounds However, all compounds I were largely less active than references compounds in the reducing power assay. The thiourea moiety probably played a crucial role in antioxidant activity of target compounds I, as a thiolate ion. The most favorable R¹ groups were hydrogen and Me, followed by Ph and benzyl, whereas most favorable R² group was iPr, followed by Ph and Me. The combination of benzothiadiazine ring with sulfonylthiourea moieties led to valuable new antioxidants, which could be used in treatment or prevention of certain diseases or in field of cosmetics, which needed further investigations in future.

And the article was included in Journal of Agricultural and Food Chemistry in 2018.HPLC of Formula: 2253-73-8 The following contents are mentioned in the article:

To characterize potent odor-active compounds in preserved egg yolk (PEY), volatile compounds were isolated by headspace solid-phase microextraction and solvent-assisted flavor evaporation Gas chromatog.-olfactometry (GC-O) and gas chromatog.-mass spectrometry (GC-MS) analyses identified a total of 53 odor-active compounds by comparing the odor characteristics, MS data, and retention indexes with those of reference compounds Twenty-seven odorants were detected in at least five isolates that were extracted and analyzed by the same method, and their flavor dilution (FD) factors, ranging from 1 to 2048, were measured by aroma extract dilution anal. (AEDA). To further determine their contribution to the overall aroma profile of PEY, 22 odorants with FD factors ≥16 and GC-MS responses were quantitated, and their odor activity values (OAVs) were calculated According to the OAV results, 19 odorants with OAVs ≥ 1 are the potent odorants that greatly contribute to the characteristic aroma of PEY. Nine compounds were identified for the first time: (E,Z)-2,6-nonadienal, (E)-2-nonenal, 2-methylbutanal, di-Me disulfide, trimethylamine, methional, di-Me trisulfide, diisopropyl disulfide, and di-Et disulfide.

High-Resolution Rotational Spectroscopy and Interstellar Search for Isopropyl Isothiocyanate was written by Xu, Yugao;Zhang, Jiaqi;Li, Wenqin;Li, Juan;Feng, Gang. And the article was included in ACS Earth and Space Chemistry in 2021.Computed Properties of C4H7NS The following contents are mentioned in the article:

The pure rotational spectrum of iso-Pr isothiocyanate was measured using a supersonic-jet Fourier transform microwave spectrometer in the frequency region of 2-20 GHz. The rotational transition assignments were extended to the monosubstituted ¹³C, one ³⁴S, and one ¹⁵N isotopic species in natural abundance. The exptl. measurements yielded accurate spectroscopic parameters including rotational constants, quantic centrifugal distortion constants, and ¹⁴N nuclear quadrupole coupling constants The determined rotational constants were used to derive the skeleton structure of iso-Pr isothiocyanate. Rotational spectroscopy and structural analyses provide unambiguous evidence that the trans form of the mol. is the global min. Based on the spectroscopic results, an astronomical search for iso-Pr isothiocyanate toward Sgr B2(N) was carried out using a Shanghai Tianma radio telescope (TMRT); however, none of the predicted rotational transitions were detected. The upper limits for the abundance of trans (CH₃)₂CHNCS relative to H₂ in Sgr B2(N) were estimated to be X((CH₃)₂CHNCS) < 8 x 10^-12.

Access to Metal-Bridged Osmathiazine Derivatives by a Formal [4+2] Cyclization was written by Li, Jinhua;Lin, Yu-Mei;Zhang, Hong;Chen, Yuan;Lin, Zhenyang;Xia, Haiping. And the article was included in Chemistry – A European Journal in 2019.Synthetic Route of C4H7NS The following contents are mentioned in the article:

Treatment of osmacyclopentadiene derivatives 1 with Ph or iso-Pr isothiocyanate gave the fused five and six-membered osmacycles 2–5 by a formal [4+2] cyclization. The facile protonation of the newly generated exocyclic imine in complexes 2–5 afforded conjugation-extended osmacycle derivatives 6–9. Compounds 2–9 each contain two main-group heteroatoms (N and S) in the fused six-membered ring located at the ortho (for S) and para (for N) positions relative to the osmium center; these species can be regarded as rare osma-1,3-thiazine derivatives and represent the first fused metallathiazine derivatives In contrast to the non-planar organic 6H-1,3-thiazine, nearly coplanar metallathiazines 8 and 9 can be achieved by tuning the groups on the two nitrogen atoms. These unique metal-bridged osma-1,3-thiazine derivatives exhibit remarkable stabilities, broad spectral absorptions spanning the visible spectra, and considerable photothermal properties, which suggests their potential applications in material science.
