Diethyl methylmalonate Chemical Properties,Uses,Production

Chemical Properties

Clear liquid


Diethyl methylmalonate was used to investigate the effect of direct supplementation of the medium with di-ester of methylmalonate on erythromycin fermentation in Saccharopolyspora erythraea mutB strain.


Diethyl methylmalonate is used as intermediate for the syntheses of pharmaceuticals, e.g. non-steroidal anti-inflammatory agents with 2-acrylpropionic acid structures acrylpropionic acid structure. It is also used in the flavour and fragrance industries. Product Data Sheet

General Description

Diethyl methylmalonate reacts with 2-cyclohexenone under abnormal Michael conditions form 2-(3-oxocyclohexyl)-2-cyclohexenone. It causes the alkylation of poly(chloromethylstyrene) during pahse transfer catalysis.
