Propyl Chloroformate(CAT: R023589) is an organic compound with the molecular formula C₄H₇ClO₂. It is a colorless to pale yellow liquid with a sharp, pungent odor and is highly reactive due to the presence of both ester and acyl chloride functional groups. Propyl chloroformate is commonly used as a reagent in organic synthesis for introducing the carbamate (–OC(O)NH–) or carbonate functional groups. It is particularly valuable in the preparation of urethanes, protecting groups for amines and alcohols, and various pharmaceutical intermediates. Due to its moisture sensitivity and corrosiveness, it should be handled with care under dry, controlled conditions.
