Description

3-Bromo-4-chlorobenzaldehyde (CAS No. 86265-88-5) is a high-purity halogenated benzaldehyde derivative with the molecular formula C7H4BrClO. This aromatic aldehyde is a versatile building block in organic synthesis, particularly in pharmaceutical, agrochemical, and materials science research. Its unique structure, featuring both bromo and chloro substituents on the benzene ring, allows for selective functionalization via cross-coupling reactions, nucleophilic substitutions, or further oxidation/reduction steps. Available in >98% purity (GC), this compound is supplied as a white to off-white crystalline powder with a characteristic aromatic odor. It is stable under recommended storage conditions (2-8°C in a tightly sealed container) but may decompose under strong light or heat. Suitable for use in Suzuki-Miyaura couplings, Grignard reactions, and as a precursor for heterocyclic compounds.
