Dimethyl oxalate, 99%

Description

CAS: 553-90-2 | C4H6O4 | 118.09 g/mol

Dimethyl oxalate is used as an alternate fuel in the direct oxidation fuel cell. It is involved in the catalytic hydrogenation using Cu/SiO₂ to prepare ethylene glycol. It is also used in the selective gas-phase hydrogenation catalyzed by Ag/SiO₂ to get the corresponding alcohol.

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.
