Application:
Diethyl Oxalate (CAS: 95-92-1) is used to prepare active pharmaceutical ingredients (API), plastics and dyestuff intermediates. It is also used as a solvent for cellulose esters, ethers, resins, perfumes and lacquers for electronics. Diethyl Oxalate is involved in the transesterification reaction with phenol to get dipheny oxalate. It is also involved in the Claisen condensation ketosteroids to prepare glyoxalyl derivatives. It is utilized in the microemulsion synthesis of zinc oxide nanoparticles. Diethyl Oxalate has the general properties of esters. It absorbs moisture in the air and decomposes slowly. It reacts with ammonia to form amide compounds and condenses with acetone to ethyl pyruvate. Diethyl Oxalate is mainly used in the pharmaceutical industry. It is an intermediate of azathioprine, peripheral sulfanilamide, carboxyphenyllipase penicillin, ethoxybenzylpenicillin, chloroquine lactate, thiabendazole, sulfamethoxazole and other drugs. It can be used as an intermediate of plastics, dyes and other products, and as a solvent of cellulose and spices. Toxic by ingestion, strong irritant to skin and mucous membranes.
