Diethyl malonate

Diethyl malonate (CAS 105-53-3 ), also known by the abbreviation DEM or as malonic ester, is a diester compound used as a synthetic intermediate and flavoring agent across food, fragrance, and specialty chemical manufacturing.

Its reactivity at the active methylene group makes it a foundational building block for producing pharmaceuticals, agrochemicals, and aroma compounds at industrial scale. In flavor and fragrance production, DEM functions as a precursor to fruity aroma compounds.

The material carries FEMA 2375 status for direct use as a flavoring ingredient. Agrochemical manufacturers rely on it as a key intermediate in synthesizing active ingredients including certain herbicides and insecticides.

In pharmaceutical synthesis, it serves as a carbon-chain extender in the production of barbiturates, amino acids, and other active pharmaceutical ingredients. Personal care formulators use it as a carrier solvent and reactive intermediate.

Diethyl malonate is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume buyers. Standard commercial grades include technical and food-grade ( FCC ) specifications.

Purity levels of 99% and above are typical for synthesis-grade material supplied to pharmaceutical and agrochemical customers. Our logistics network ensures reliable delivery of high-purity esters for diverse industrial applications.
