Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of benzothiazole-based drugs with potential antimicrobial, antiviral, and anticancer activities. It serves as a building block in the preparation of fluorescent dyes and optical brighteners due to the inherent fluorescence of the benzothiazole core. Also employed in the fabrication of organic semiconductors and materials for optoelectronic devices. Its bromo and amino functional groups allow for further chemical modifications through cross-coupling reactions and nucleophilic substitutions, making it valuable in medicinal chemistry and materials science research.
