Used as an intermediate in organic synthesis, particularly in the preparation of fluorescent dyes and optoelectronic materials. Its brominated structure allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in the development of organic semiconductors and luminescent compounds. Commonly employed in the design of benzothiazole-based conjugated systems for use in OLEDs and fluorescent probes. Also explored in pharmaceutical research for building bioactive heterocyclic compounds due to the benzothiazole core’s prevalence in medicinal chemistry.
