Used in organic synthesis as a building block for creating complex molecules, particularly in pharmaceutical research. It serves as an intermediate in the development of compounds with potential biological activity, such as antimicrobial, anti-inflammatory, or anticancer agents. The bromine atom and carboxylic acid groups make it a versatile reagent for coupling reactions and further functionalization. Its structure is valuable in designing ligands for metal complexes, which can be applied in catalysis or material science. Additionally, it is utilized in the preparation of quinoline-based dyes and pigments for industrial applications.
