2-Bromo-4-chlorobenzaldehyde (CAS 84459-33-6) is a substituted aromatic aldehyde supplied by TCI, commonly used as a key intermediate in organic synthesis. It serves as a building block for pharmaceutical, agrochemical, and fine chemical compounds, particularly in the construction of heterocyclic structures. The presence of bromo and chloro substituents makes it a suitable substrate for transition-metal-catalyzed cross-coupling reactions and aldehyde condensation reactions.
