Application

2-Bromo-4-chlorobenzoic acid serves as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs) and specialty chemicals. It is particularly valuable in constructing complex molecules through palladium-catalyzed coupling reactions. Researchers utilize this compound in medicinal chemistry for structure-activity relationship (SAR) studies due to its halogenated aromatic core. The carboxylic acid group allows for further functionalization via esterification or amidation reactions. Its dual halogen substitution pattern enables selective sequential derivatization in multi-step syntheses.
