Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and analgesic agents. Its structure supports binding to biological targets involved in pain and inflammation pathways. It is also employed in the preparation of fluorescent probes due to the presence of the benzothiazole moiety, which can enhance optical properties in sensing applications. Additionally, derivatives of this compound have shown potential in agricultural chemicals as active ingredients in fungicides and plant growth regulators.
