4-Chloro-3-oxobutanoyl chloride

Description:

4-Chloro-3-oxobutanoyl chloride, with the CAS number 41295-64-1, is an organic compound characterized by its acyl chloride functional group, which is known for its reactivity and ability to form esters and amides. This compound features a chloro substituent at the fourth carbon position and a ketone group at the third carbon, contributing to its electrophilic nature. It is typically a colorless to pale yellow liquid, exhibiting a pungent odor, which is common for acyl chlorides due to the presence of the reactive carbonyl group. The compound is soluble in organic solvents such as dichloromethane and ether but is generally not soluble in water due to its hydrophobic characteristics. It is important to handle this substance with care, as it can be corrosive and may react violently with water, releasing hydrochloric acid. 4-Chloro-3-oxobutanoyl chloride is often used in organic synthesis, particularly in the preparation of various chemical intermediates and pharmaceuticals.
