Methyl chloroformate is the methyl ester of chloroformic acid and is an oily liquid with a color that is anywhere from yellow to colorless. It is also known for its pungent odor.
Uses
Methyl chloroformate is used in organic synthesis for the introduction of the methoxycarbonyl functionality to a suitable nucleophile (i.e. carbomethoxylation).[2]
Safety
Methyl chloroformate, if heated, releases phosgene and produces toxic, corrosive fumes if it comes in contact with water.
