Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antimicrobial agents. It serves as a building block in heterocyclic chemistry due to its reactive hydrazine and benzothiazole groups, enabling the formation of various fused ring systems. Also employed in the preparation of dyes and fluorescent compounds for use in analytical chemistry and sensors. Its derivatives show potential in coordination chemistry as ligands for metal ions in catalytic applications.
