Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with antimicrobial, antifungal, anti-inflammatory, and anticancer properties. The bromine and carboxylic acid groups enable facile further reactions, such as nucleophilic substitution or amide formation, making it suitable for structural modifications in laboratory settings. Its benzothiazole structure serves as a key building block in heterocyclic chemistry, enabling the construction of complex organic compounds. Commonly employed in medicinal chemistry for derivatization to enhance binding affinity and selectivity in drug candidates. Also utilized in the preparation of fluorescent probes and optoelectronic materials due to the inherent electronic properties of the benzothiazole core.
