Applications

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.

Notes

Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents.

Literature References
