Used in the synthesis of fluorescent dyes and optical brighteners due to its rigid aromatic structure and ability to participate in conjugation. Its amino and carbonyl functional groups allow for Schiff base formation, making it valuable in coordination chemistry for developing metal ion sensors. Also employed as an intermediate in pharmaceuticals, particularly in the production of antitumor and antimicrobial agents. The compound’s benzothiazole core contributes to bioactivity, enabling applications in medicinal chemistry for designing enzyme inhibitors. Additionally, it serves as a building block in organic electronics and luminescent materials.
