Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its reactive sulfonyl chloride group allows for easy attachment to other molecules, making it valuable in creating sulfonamide derivatives. Commonly employed in cross-coupling reactions due to the presence of bromo and chloro substituents, enabling selective functionalization in complex molecule assembly. Also utilized in research settings for designing kinase inhibitors and other bioactive compounds.
