Methyl 2-(methylsulfonyl)acetate (cas: 62020-09-1) 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 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. COA of Formula: C4H8O4S

Synthesis and polymerization of alkyl α-(Alkylsulfonyl)acrylates was written by Gipstein, E.;Willson, C. G.;Sachdev, H.. And the article was included in Journal of Organic Chemistry in 1980.COA of Formula: C4H8O4S This article mentions the following:

The reaction of RSO2CHMeCO2R1 (R = Me, CMe3; R1 = CMe3, Me) with PhSeCl gave RSO2C(SePh)MeCO2R1, the selenide products were treated with H2O2, and Se-oxidation was followed by an elimination reaction to yield the resp. RSO2C:(CH2)CO2R1 (I). The deacylative methylenation of MeSO2CH(COPh)CO2Me by HCHO gave I (R = R1 = Me). The I (R1 = Me) polymerized more readily than the I (R1 = CMe3). In the experiment, the researchers used many compounds, for example, Methyl 2-(methylsulfonyl)acetate (cas: 62020-09-1COA of Formula: C4H8O4S).
