Used primarily as an intermediate in the synthesis of agricultural chemicals, particularly herbicides and fungicides. It plays a key role in the production of crop protection agents due to its ability to enhance the biological activity of final pesticide formulations. Additionally, it serves as a building block in the development of certain pharmaceuticals and dyes, where the chlorinated benzothiazole structure contributes to stability and reactivity. Its derivatives are also explored in research for agrochemical innovation and material science applications.
