Diethyl oxalate, 99%

Description

CAS: 95-92-1 | C6H10O4 | 146.142 g/mol

Diethyl oxalate 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. It 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. Further, it is used to prepare sym-1,4-diphenyl-1,4-dihydro-1,2,4,5-polytetrazine. In addition to this, it is utilized in the microemulsion synthesis of zinc oxide nanoparticles.

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.
