Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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.

Characterization of volatile and semi-volatile compounds in Chinese rice wines by headspace solid phase microextraction followed by gas chromatography-mass spectrometry was written by Luo, Tao;Fan, Wenlai;Xu, Yan. And the article was included in Journal of the Institute of Brewing in 2008.Related Products of 763-69-9 The following contents are mentioned in the article:
The volatile and semi-volatile compounds of Chinese rice wines were extracted by headspace solid phase microextraction (HS-SPME) and analyzed by gas chromatog.-mass spectrum (GC-MS). The original Chinese rice wine samples were diluted with deionized water to a final concentration of 6% (volume/volume) ethanol and then extracted by HS-SPME. The samples were pre-equilibrated at 50°C for 15 min and extracted with stirring at the same temperature for 45 min prior to injection into a GC-MS. A total of 97 volatile and semi-volatile compounds were identified from ten Chinese typical rice wine samples, including 13 alcs., 8 acids, 28 esters, 4 aldehydes and ketones, 17 aromatic compounds, 3 lactones, 6 phenols, 3 sulfides, 9 furans and 6 nitrogen-containing compounds, of which, 39 compounds were firstly reported in Chinese rice wine. By stepwise linear discrimination anal., the ten Chinese rice wine samples could be classified into three groups according to the production area, and in particular, the production technologies. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Related Products of 763-69-9).
