Product Overview

• Diethyl Oxalate is the diethyl ester of oxalic acid, a colorless to pale yellow, mobile liquid with a mild, faintly fruity odor, widely used as a chemical intermediate across pharmaceutical, agrochemical, and dye manufacturing sectors. Chemically classified as a dicarboxylic acid ester, it is miscible with most organic solvents and slowly hydrolyzes in the presence of water, particularly under acidic or alkaline conditions. Procorbay International supplies industrial-grade Diethyl Oxalate at high purity, serving as a key building block in Claisen condensation reactions and other organic synthesis pathways where its reactive ester groups enable efficient construction of heterocyclic and carbonyl-containing target molecules.

• Diethyl Oxalate is manufactured through the esterification of oxalic acid with ethanol under acid catalysis, followed by distillation to achieve the required purity for industrial synthesis applications. Procorbay sources Diethyl Oxalate from established fine and specialty chemical manufacturers maintaining consistent quality control over purity, moisture content, and acid value.
• Industrially, Diethyl Oxalate is one of the most widely used oxalate esters in organic synthesis, valued for its role as a two-carbon building block in Claisen condensation reactions to construct beta-ketoester intermediates used in pharmaceutical and agrochemical active ingredient synthesis. It also serves as a solvent and reactive intermediate in dye and pigment manufacturing, and in the production of oxalate-derived specialty chemicals. Given its consistent demand from pharmaceutical and agrochemical intermediate manufacturers, Procorbay maintains dependable supply to serve chemical synthesis operations requiring reliable batch quality.
