Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antitumor and antiviral agents. Its structure supports the creation of biologically active compounds due to the presence of the benzothiazole core and the methylsulfonyl group, which enhances electron-withdrawing properties and improves binding to target enzymes. Also employed in agrochemical research for designing novel pesticides with improved efficacy and selectivity. Additionally, it serves as a building block in materials science for developing organic semiconductors and fluorescent dyes.
