Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals and agrochemicals. Its structure supports the development of compounds with antimicrobial, antifungal, and anti-inflammatory properties. Commonly employed in medicinal chemistry for designing kinase inhibitors and fluorescent probes due to the strong electron-withdrawing nature of the benzothiazole ring and the stability provided by the toluidine moiety. Also utilized in materials science for developing organic semiconductors and luminescent materials.
