Benzyl Carbamate (Z-NH2) (CAS: 621-84-1), insoluble in water, soluble in organic solvents such as benzene.
Benzyl Carbamate is a reagent used for the nucleophilic introduction of an amino-protected group, Benzyl carbamates can be considered as a benzyloxycarbonyl (otherwise known as carbobenzyloxy, Cbz or Z) protecting group for amino groups. It was introduced as a versatile alternative to the ethoxy carbamate group in peptide synthesis. Used as organic synthesis intermediates.
Benzyl Carbamate is an intermediate in the synthesis of various pharmaceutical compounds. It can be also used as nondeuterated internal standards for the quantitative analysis of carisoprodol in blood.
Preparation Benzyl carbamate is prepared by reacting benzyl chloroformate with ammonia. Benzyl chloroformate was slowly added to 5 times the volume of cold ammonia water (relative density 0.90) under vigorous stirring, the reaction mixture was placed at room temperature for 30 minutes, the precipitate was filtered out, washed with water and dried to obtain the finished product of benzyl carbamate.
