Used as an intermediate in the synthesis of agricultural chemicals, particularly herbicides and fungicides. It plays a key role in the production of chlorinated benzothiazole derivatives that exhibit biological activity against plant pathogens. Also utilized in the development of dyes and fluorescent whiteners due to its heterocyclic structure with electron-donating and withdrawing groups. Its amino and chloro functionalities allow for further chemical modifications, making it valuable in organic synthesis and pharmaceutical research.
