CAS 79-22-1: Methyl chloroformate

Description: Methyl chloroformate, with the CAS number 79-22-1, is an organic compound classified as an acyl chloride. It is a colorless to pale yellow liquid with a pungent odor, reminiscent of esters. This compound is known for its reactivity, particularly as a reagent in organic synthesis, where it is often used to introduce the chloroformate functional group into various substrates. Methyl chloroformate is soluble in organic solvents such as ether and acetone but is less soluble in water. It is highly volatile and can pose health risks; therefore, it should be handled with care, as it can cause irritation to the skin, eyes, and respiratory system. Additionally, it is flammable and should be stored away from heat sources and open flames. Due to its reactivity, it can participate in nucleophilic acyl substitution reactions, making it valuable in the synthesis of pharmaceuticals and agrochemicals. Proper safety measures, including the use of personal protective equipment, are essential when working with this compound.
