Dimethyl carbonate, 99%, Thermo Scientific Chemicals

Description

Dimethyl carbonate is used as a solvent in organic synthesis and considered as a replacement for solvent like methyl ethyl ketone, tert-butyl acetate and parachlorobenzotrifluoride. It is involved as an intermediate in the preparation of diphenylcarbonate, which in turn is used as a key raw material for the synthesis of Bisphenol-A-polycarbonate. It is also used as a 'green' methylating agent involved in the methylation of aniline, phenols and carboxylic acids. It can be used as a fuel additive due to its high oxygen content. It also finds applications related to supercapacitors and lithium 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.
