Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. It serves as a building block in the preparation of bioactive molecules, particularly in the development of compounds with potential antimicrobial, antifungal, or anti-inflammatory properties. The bromo and ester functionalities allow for further chemical modifications, such as cross-coupling reactions and nucleophilic substitutions, making it valuable in medicinal chemistry research. Also employed in the synthesis of heterocyclic compounds containing the benzothiazole ring, which are of interest in materials science and drug discovery.
