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.

Safety of food contact silicone rubber: liberation of volatile compounds from soothers and teats was written by Lund, Kirsten H.;Petersen, Jens Hojslev. And the article was included in European Food Research and Technology in 2002.Quality Control of Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:

The release of volatile compounds from infant pacifiers and bottle nipples made from silicone rubber has been investigated. Measurements of the total release of volatiles were performed according to the method in the draft European standard (CEN). Weight losses of 0.17-0.80% after four hours at 200°C were observed using gravimetric measurements. One product had a weight loss above the proposed CEN limit of 0.5%. The volatile compounds were identified using a thermal desorption/cold trap injector on a gas chromatograph equipped with IR spectroscopic (IR) and mass spectrometric (MS) detectors. The main compounds were siloxane oligomers and aliphatic hydrocarbons. One teat released about 0.1 mg di-Et phthalate (DEP), which is considered to be quite a high quantity. Limited amounts of the antioxidant 3,5-di-t-butyl-4-hydroxytoluene (BHT) were found in most samples. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Quality Control of Ethyl 3-ethoxypropanoate).
