Basic Info

Benzyl chloroformate is the benzyl ester of chloroformic acid. It is also known as benzyl chlorocarbonate and is an oily liquid whose color is anywhere from yellow to colorless. It is also known for its pungent odor. When heated, benzyl chloroformate decomposes into phosgene and if it comes in contact with water it produces toxic, corrosive fumes.
