Phenyl chloroformate is used in the synthesis of poly(2-(phenoxycarbonyloxy)ethyl methacrylate) and phenyl-(4-vinylphenyl) carbonate. It acts as a precursor of phenyl mixed anhydrides which are used in peptide coupling reactions. It serves as a dehydrating reagent for the conversion of primary amides to nitriles and an intermediate in the synthesis of pharmaceuticals and carbamates.

Miscible with N,N-dimethylformamide.

Store in cool place. Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with bases, alcohols and amines. Hydrolyses in water.
