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.
High-boiling dipolar aprotic solvent. The polar nature, wide liquid range and high solvent power of tetraalkylureas make them suitable solvents for a wide range of reactions; review: Angew. Chem. Int. Ed., 18, 503 (1979).
