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(CAS NO:501-53-1) is used in organic synthesis for the introduction of the carboxybenzyl (Cbz or Z) protecting group for amines.The newly formed Cbz protecting group can be removed under reductive conditions. Typically hydrogen gas and activated palladium on carbon is used.

Chemical dangers Decomposes on heating. Benzyl Chloroformate phosgene. Decomposes on contact with water. Benzyl Chloroformate toxic and corrosive fumes including hydrogen chloride (see ICSC 0163). Attacks many metals in the presence of water or moist air. The substance can be absorbed into the body by inhalation and by ingestion. A harmful concentration of airborne particles can be reached quickly on spraying.Lachrymation. Benzyl Chloroformate is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the aerosol may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated. Notes The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
