Benzyl chloroformate is the benzyl ester of chloroformic acid. It is also known as benzyl chlorocarbonate is an oily liquid who color is anywhere from yellow to colorless. It is also known for its pungent odor. Benzyl chloroformate if heated turns into a phosgene and if it comes in contact with water it produces toxic, corrosive fumes.
Benzyl chloroformate is used in organic synthesis for the introduction of the carboxybenzyl (Cbz,Z) protecting group for amines. It also is a carcinogen.[citation needed]
