Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It plays a key role in the production of rubber vulcanization accelerators, particularly in manufacturing sulfur-containing compounds that improve the durability and elasticity of rubber products. Also utilized in the development of dyes and pigments due to its reactive amine group and heterocyclic structure. Its chlorinated benzothiazole core makes it valuable in forming bioactive molecules in medicinal chemistry research.
