Diethyl oxalate

Diethyl oxalate (CAS 95-92-1), also known as ethyl oxalate, is the diethyl ester of oxalic acid used primarily as a chemical intermediate and solvent in organic synthesis. It functions as a reactive building block for introducing the oxalyl group into target molecules.

The compound serves as a catalyst precursor in specialty chemical manufacturing and industrial processes. In pharmaceutical synthesis, it acts as a key condensation reagent for producing active pharmaceutical ingredients, particularly in the manufacture of barbiturates and antimalarials.

It is also utilized in the production of other heterocyclic compounds. Formulators in personal care use it as a fragrance ingredient and fixative, where its mild ester character contributes to scent profiles in fine fragrances and cosmetic products.

As a FEMA-recognized flavoring agent, it is incorporated at controlled levels in food flavor compositions to impart fruity, wine-like nuances. In catalysis applications, it acts as an oxalate precursor for preparing metal oxalate catalyst supports.

The product is also used as an intermediate in various industrial chemical processes. Diethyl oxalate is supplied as a clear liquid in standard commercial packaging ranging from drums to IBC containers for bulk distribution.

Technical grade and high-purity grades are available to meet the differing requirements of industrial synthesis versus pharmaceutical and flavor applications. Buyers sourcing for regulated end uses should confirm grade specifications and purity certificates.
