The English name for dimethyl malonate is Dimethyl malonate, which is a general organic reagent. Dimethyl malonate is an important raw material for the production of the pharmaceutical drug pipemidic acid. Internationally, dimethyl malonate is primarily used as a raw material for the non-ethoxymethylene process to produce pipemidic acid, reacting with orthoformate and urea to yield pipemidic acid.

Applications
　　　1. Use: Used in pharmaceuticals and organic synthesis.
　　　2. Use: Dimethyl malonate is an important raw material for the production of the pharmaceutical drug pipemidic acid. Internationally, dimethyl malonate is mainly used as a raw material for the non-ethoxymethylene process to produce pipemidic acid, reacting with orthoformate and urea to yield pipemidic acid. Currently, in China, the majority of dimethyl malonate produced by related enterprises, aside from exports, is used to manufacture pipemidic acid.
