ClCOCH2Cl

ClCOCH2Cl, also known as chloroacetyl chloride or 2-chloroacetyl chloride, is an organochlorine compound with the chemical formula ClCOCH2Cl. It is a colorless liquid with a pungent odor. It is a reactive acyl halide and a bifunctional molecule, containing both a carbonyl group and a chloroalkyl group.

Chloroacetyl chloride is a strong lachrymator, meaning it irritates the eyes and causes tearing. It is also corrosive and can cause severe burns on contact with skin and mucous membranes. Due to its reactivity, it is typically handled with care in well-ventilated areas and with appropriate personal protective equipment.

This compound is primarily used as an intermediate in organic synthesis. It serves as a building block for the production of a variety of chemicals, including pharmaceuticals, pesticides, dyes, and other specialty chemicals. Its reactivity allows for the introduction of the chloroacetyl group into other molecules through reactions such as acylation. For example, it can react with alcohols to form chloroacetate esters or with amines to form chloroacetamides. These derivatives are often more stable and can be further manipulated to create more complex molecular structures.
