Product Name:Diethyl malonate
English Name:Diethyl malonate
CAS No.:105-53-3
Aliases:Diethyl propanedioate, Ethyl malonate, Propanedioic acid diethyl ester
Molecular Formula:C7H12O4
Physical Properties:Colorless liquid with a slight sweet ester-like odor. Melting point -50°C, boiling point 199°C, relative density (water=1) 1.055, refractive index 1.413-1.415, flash point 90°C. Slightly soluble in water; miscible with ethanol, ether, benzene and other organic solvents.
Uses:An organic synthesis intermediate widely used in the production of pharmaceuticals, dyes, fragrances, and sulfonylurea herbicides. It is mainly used to prepare ethoxymethylene, barbituric acid, and alkyl diethyl malonates, which are further converted into drugs such as norfloxacin, chloroquine, and phenylbutazone, as well as benzimidazolone organic pigments. It also serves as a plasticizer for nitrocellulose.
