Chloromethyl chloroformate is an organic compound with the formula C₂H₂Cl₂O₂. It is a highly reactive chloroformate ester containing both a chloromethyl group and a chloroformate (–OCOCl) functional group. This makes it useful as a reagent in organic synthesis, particularly for introducing protective groups or forming carbamates and carbonates. Due to its strong reactivity and toxicity, it must be handled with strict safety precautions.
