Descrizione

CAS: 632-22-4 | C5H12N2O | 116.164 g/mol

Tetramethylurea is used as a solvent in dyestuff industries, in condensation reaction and intermediates in surfactant. It is utilized for base catalyzed isomerization and alkylation hydrocyanation due to its low permittivity. It reacts with oxalyl chloride to prepare tetramethyl chloroformamidinium chloride, which is used for the conversion of carboxylic acids and dialkyl phosphates to anhydrides and pyrophosphates respectively.

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.
