Oxalic acid ethyl ester（Cat No.:R014120）, also known as diethyl oxalate, is a diester formed from oxalic acid and ethanol. It appears as a colorless, oily liquid with a mild, pleasant odor and is soluble in organic solvents like ethanol, ether, and acetone. Diethyl oxalate is widely used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals, dyes, agrochemicals, and heterocyclic compounds. It also serves as a reagent in the formation of oxamide and as a stabilizer in plastics. It should be handled with care due to potential irritant properties.
