Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. It serves as a building block in the development of kinase inhibitors and antimicrobial agents due to its isothiazole core, which enhances binding affinity to enzyme active sites. Its bromine functionality allows for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship studies. Also employed in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
