Application
4-Bromo-2-chlorobenzoic acid serves as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly non-steroidal anti-inflammatory drugs (NSAIDs) and antimicrobial agents. Its dual halogen functionality enables selective derivatization for creating complex molecular architectures in medicinal chemistry. The compound is also employed in material science for developing liquid crystal displays (LCDs) and organic semiconductors. Researchers value its utility in constructing benzodiazepine scaffolds and other heterocyclic systems through palladium-catalyzed coupling reactions.
