Product Description

China Manufacturer Supply Diethyl Malonate / Ethyl Malonate CAS 105-53-3

Diethyl malonate (DEM) is a diethyl ester of malonic acid, a colorless, apple-flavored liquid that occurs naturally in grapes and strawberries. It is a β-dicarbonyl compound, used as an intermediate in organic synthesis and drug synthesis, and can synthesize barbiturates, vitamin B1, vitamin B6 and artificial flavors. Similar compounds are ethyl acetoacetate, dimethyl malonate, etc. Diethyl malonate can be prepared by using chloroacetic acid as raw material, carburizing cyanide ions and esterifying it with ethanol.Diethyl malonate or substituted diethyl malonate undergoes "keto decomposition" or "acid decomposition" to obtain acetic acid or acetic acid derivatives.

Diethyl malonate is an important fine chemical raw material. Because the methylene hydrogen in its molecule is easily replaced by a variety of groups, and then generates a variety of important derivatives, it is widely used in various chemical production. fields, including industrial dyes, liquid crystal materials and other industries.
