Description

Dimethyl malonate' is a diester derivative of malonic acid. It is a common reagent for organic synthesis, e.g. as a precursor for barbituric acid. It is used in the malonic ester synthesis. It can be synthesized from dimethoxymethane and carbon monoxide.
Dimethyl malonate is used extensively in the fragrance industry as a raw material in the synthesis of jasmonates. For example, methyl dihydrojasmonate, sold under the tradename Hedione by Firmenich, is synthesized from cyclopentanone, pentanal, and dimethyl malonate. Hedione is used in almost all fine fragrances, and is found in Christian Dior's Eau Sauvage and "Diorella", Hermes' "Voyage d'Hermes Parfum", Calvin Klein's "CKOne", Chanel's "Chanel No. 19", and Mark Jacob's "Blush", among others. As of 2009, Hedione was Firmenich's top selling compound by volume.
Hebei Chengxin is the world's largest producer of dimethyl malonate by volume and uses a chloroacetic acid/sodium cyanide process developed in the 1940s. The 2015 Tianjin explosions in China were due, in part, to storage of cyanide produced by Hebei Chengxin in a port warehouse. Both cyanide and chloroacetic acid are included on the List of extremely hazardous substances defined by the U.S. federal government. GoodGuide evaluated chloroacetic acid as one of the most hazardous chemicals (worst 10%) to ecosystems and human health.
