Used as an intermediate in organic synthesis, particularly in the preparation of functionalized phthalates for pharmaceuticals and agrochemicals. It serves as a building block in the development of fluorescent dyes and optical brighteners due to its aromatic structure. Also employed in research settings for bromination studies and cross-coupling reactions, where the bromine atom allows for further functionalization via metal-catalyzed reactions. Its ester groups enable hydrolysis or transesterification to modify solubility and reactivity in specialty polymers and plasticizers.
