Ethyl 2-hydroxybenzoate (cas: 118-61-6) 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. 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. Recommanded Product: Ethyl 2-hydroxybenzoate

Identification of volatile and odor-active compounds in Hunan black tea by SPME/GC-MS and multivariate analysis was written by Yin, Xia;Huang, Jian’an;Huang, Jing;Wu, Wenliang;Tong, Tong;Liu, Shujuan;Zhou, Lingyun;Liu, Zhonghua;Zhang, Shuguang.

Hunan black tea is well-known for its floral-honey aroma, but the volatile components responsible for the fragrance have not been elucidated yet. In this study, the volatile compounds in Hunan black tea were identified and quantified by the headspace solid-phase microextraction coupled with gas chromatog.-mass spectrometry (HS-SPME-GC-MS). The results showed that 88 compounds were extracted and determined in Hunan black tea, including the dominant components Geraniol, phenethyl alc., phenylacetaldehyde, linalool, nonanal and other 5 aromatic compounds Furthermore, the aroma-active compounds were identified by odor activity value (OAV). It was found that 24 aroma compounds, including geraniol with an OAV� were regarded as the primary active aromatic compounds in Hunan black tea. Finally, partial least squares (PLS) regression anal. was employed and results revealed that Nonanal, trans-nerolidol, benzyl alc., and phenylethanol exhibit a pos. correlation with the intensity of floral and sweet honey aromas. Overall, this study identified the volatile compounds responsible for the dominant floral-honey aroma in Hunan black tea. In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxybenzoate (cas: 118-61-6Recommanded Product: Ethyl 2-hydroxybenzoate).
