High-purity Dimethyl Malonate Ester 99.5%

Dimethyl Malonate (DMM) – Premium Diester for Organic Synthesis (99.5% Purity)   Specification: 200kg/drum   Dimethyl malonate, commonly abbreviated as DMM and systematically named dimethyl propanedioate, is a colorless, clear liquid with a faint, sweet, fruity odor. Our premium product achieves 99.5% purity, delivering exceptional quality for pharmaceutical synthesis, agrochemical manufacturing, flavor and fragrance production, and advanced organic chemistry applications.   As the simplest diester of malonic acid, dimethyl malonate possesses unique chemical reactivity centered on the active methylene group positioned between two electron-withdrawing ester functionalities. This 1,3-dicarbonyl arrangement creates highly acidic α-protons (pKa ~13), enabling facile enolate formation and nucleophilic substitution reactions that are fundamental to carbon-carbon bond formation in organic synthesis. The two methyl ester groups provide versatility in subsequent hydrolysis and decarboxylation t…
