kloroacetofenon

Kloroacetofenon, also known as phenacyl chloride, is an organochlorine compound with the chemical formula C8H7ClO. It is a solid at room temperature, appearing as colorless to pale yellow crystals. It has a pungent, irritating odor. Kloroacetofenon is a derivative of acetophenone, where a chlorine atom is substituted onto the alpha carbon of the acetyl group.

This compound has seen limited use as a chemical intermediate in organic synthesis. Historically, it was employed as a lachrymator, meaning it causes tearing, and was investigated for riot control applications. However, its irritant properties and potential for toxicity have led to its replacement by other agents in such applications. It is important to handle kloroacetofenon with caution due to its hazardous nature. Exposure can cause severe irritation to the eyes, skin, and respiratory tract.
