2-Chloro-4-fluorobenzoic acid was used in the preparation of 2-(2-chloro-4-fluorophenyl)-benzothiazole.
2-Chloro-4-fluorobenzoic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling direct incorporation of ortho-chloro and meta-fluoro substituents into aromatic scaffolds. Its carboxylic acid functionality facilitates facile derivatization via amide, ester, or acyl chloride formation, while the halogen atoms support subsequent palladium-catalyzed cross-coupling reactions. The compound exhibits good bench stability and is readily purified by recrystallization, making it well-suited for high-throughput synthetic workflows.
