2-Chloro-5-methylbenzoyl chloride

Description:

2-Chloro-5-methylbenzoyl chloride, with the CAS number 21900-50-5, is an organic compound that belongs to the class of acyl chlorides. It features a benzene ring substituted with a chlorine atom at the 2-position and a methyl group at the 5-position, along with a carbonyl group (C=O) bonded to a chlorine atom. This compound is typically a colorless to pale yellow liquid with a pungent odor, characteristic of acyl chlorides. It is known for its reactivity, particularly in nucleophilic acyl substitution reactions, making it useful in organic synthesis, especially for the preparation of various derivatives and intermediates in pharmaceuticals and agrochemicals. 2-Chloro-5-methylbenzoyl chloride is sensitive to moisture and can hydrolyze in the presence of water, releasing hydrochloric acid. Proper handling and storage in a dry environment are essential to maintain its stability and prevent unwanted reactions. Safety precautions should be taken due to its corrosive nature and potential health hazards upon exposure.
