Its primary use is as a beverage preservative and or processing aid or sterilant (INS No. 242), and acts by inhibiting the enzymes acetate kinase and L-glutamic acid decarboxylase. It has also been proposed that methoxycarbonylation of the histidine part of the enzymes alcohol dehydrogenase and glyceraldehyde 3-phosphate dehydrogenase by DMDC inhibits these essential enzymes also. Once it has been added to beverages, the efficacy of the chemical is provided by the following reactions:. Dicarbonic acid, c,c'-dimethyl ester Dicarbonic acid, dimethyl ester Dimethyl dicarbonate Dimethyl oxydiformate Dimethyl pyrocarbonate DMPC Formic acid, oxydi-, dimethyl ester Formic acid, oxydi-, dimethyl ester (7CI,8CI) Methyl pyrocarbonate Pyrocarbonic acid dimethyl ester Velcorin C4H6O5 134.0874 134.021523302 dimethyl dicarbonate dimethyl dicarbonate 4525-33-1 COC(=O)OC(=O)OC InChI=1S/C4H6O5/c1-7-3(5)9-4(6)8-2/h1-2H3 GZDFHIJNHHMENY-UHFFFAOYSA-N belongs to the class of organic compounds known as organic carbonic acids and derivatives.
