Used as an intermediate in the synthesis of fluorescent dyes and pigments, particularly in the production of phthalocyanine-based colorants. It serves as a building block in organic synthesis for pharmaceuticals and agrochemicals due to the reactivity of the bromo and carboxylic acid functional groups. The compound is also employed in the preparation of coordination compounds and metal-organic frameworks (MOFs) where its aromatic structure and substituents facilitate complexation with metal ions. Additionally, it finds use in research settings for modifying molecular structures to enhance photophysical properties in luminescent materials.
