Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactive acid chloride group allows for easy formation of amide and ester bonds, making it valuable in constructing complex organic molecules. Commonly employed in the development of active pharmaceutical ingredients (APIs), especially in drugs targeting central nervous system disorders and anti-inflammatory agents. Also utilized in the preparation of specialty chemicals where halogen substitution enhances biological activity or metabolic stability. Its bromo and fluoro substituents facilitate further functionalization through cross-coupling reactions, expanding its utility in medicinal chemistry and process research.
