Diethyl carbonate is esters, beta-enamino esters, carbamates and unsymmetrical alkyl carbonates. It is an active component of electrolytes used in lithium which is used as a solvent for cellulose ethers, nitro cellulose, natural and synthetic resin and in erythromycin intramuscular injections. It is also used in the synthesis of 3-ethyl-4-methyl-5-phenyl-3H-oxazol-2-one, phenobarbital, pyrethrum batteries.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
