Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Safety of Ethyl 3-ethoxypropanoate

Volatile profile characterisation of Chilean sparkling wines produced by traditional and Charmat methods via sequential stir bar sorptive extraction was written by Ubeda, C.;Callejon, R. M.;Troncoso, A. M.;Pena-Neira, A.;Morales, M. L.. And the article was included in Food Chemistry in 2016.Safety of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

The volatile compositions of Charmat and traditional Chilean sparkling wines were studied for the first time. For this purpose, EG-Silicone and PDMS polymeric phases were compared and, afterwards, the most adequate was selected. The best extraction method turned out to be a sequential extraction in the headspace and by immersion using two PDMS twisters. A total of 130 compounds were determined In traditional Chilean sparkling wines, Et esters were significantly higher, while acetic esters and ketones were predominant in the Charmat wines. PCA and LDA confirmed the differences in the volatile profiles between the production methods (traditional vs. Charmat). This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Safety of Ethyl 3-ethoxypropanoate).

And the article was included in Tetrahedron in 2011.Application In Synthesis of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

Synthesis of novel 4-unsubstituted dihydropyrimidines (DPs) was performed. Subsequently, a variety of 4-unsubstituted 1,4(3,4)-DPs with amino moieties at position-2 were obtained in excellent yields by activation of position-2 owing to regioselective alkoxycarbonylation at position-3 of the DP skeleton. 3-Oxo-2-phenyl-2,3,5,8-tetrahydro[1,2,4]triazolo[4,3-a]pyrimidine was obtained using phenylhydrazine instead of amines. Individual tautomers of 1,4(3,4)-DP were observed in the 1H NMR spectra of one derivative depending on temperature and concentration On the other hand, only 1,4-DP was found in the solid state by single-crystal X-ray crystallog.

Cao, Xian-Ting et al. published their research in Advanced Synthesis & Catalysis in 2022 | CAS: 2253-73-8

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. 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.COA of Formula: C4H7NS

Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols.

A long-existing problem of cyclohexane-1,3-dione synthesis from unreactive acetone through consecutive Michael-Claisen process was solved. The practical applicability of this process was tested for 3-(2,4-dioxocyclohexyl)propanoate for �0-g scale. Furthermore, the scope of different acetone derivatives was investigated and resulted with a similar consecutive Michael-Claisen process for CDD synthesis.

Tang, Bo et al. published their research in Chirality in 2020 | CAS: 106-73-0

Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.
