Description:
3-Bromo-4-chlorobenzoyl chloride, with the CAS number 21900-34-5, is an organic compound characterized by the presence of both bromine and chlorine substituents on a benzoyl chloride structure. It features a benzene ring with a carbonyl group (C=O) attached to a chlorine atom and a bromine atom at the 3 and 4 positions, respectively. This compound is typically a colorless to pale yellow liquid or solid, depending on its purity and temperature. It is known for its reactivity, particularly due to the presence of the acyl chloride functional group, which makes it a useful intermediate in organic synthesis, especially in the preparation of various pharmaceuticals and agrochemicals. The compound is sensitive to moisture and can hydrolyze in the presence of water, releasing hydrochloric acid. Safety precautions are necessary when handling this substance, as it can be corrosive and may cause irritation to the skin, eyes, and respiratory system. Proper storage in a cool, dry place away from moisture is recommended to maintain its stability.
