Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of biologically active compounds. Its structure serves as a building block in heterocyclic chemistry, enabling the formation of more complex molecules with potential antimicrobial, antifungal, or insecticidal properties. Commonly employed in coupling reactions to introduce the benzo[d]thiazole moiety into target compounds, it plays a role in the creation of dyes, fluorescent agents, and functional materials. Its halogen substituents allow for selective functionalization through cross-coupling techniques like Suzuki or Heck reactions, making it valuable in medicinal chemistry research and development.
