Versatile Chemical Building Block C₈H₁₄O₅

Diethyl malate​ CAS 7554-12-3 is the diethyl ester of malic acid, a naturally occurring dicarboxylic acid. It is a clear, colorless to pale yellow liquid ester with a characteristic, mild fruity odor. Its structure consists of a four-carbon malate backbone (HOOC-CH2-CH(OH)-COOH) where both carboxylic acid groups are esterified with ethanol.Diethyl Malate is a multifunctional, bio-based ester​ that uniquely serves as a high-performance green solvent, a pleasant flavor/fragrance precursor, and a versatile chemical building block. Its combination of safety, sustainability, and dual functional group reactivity makes it a superior choice for modern, eco-conscious formulations.
