Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves in the preparation of bioactive molecules due to the presence of multiple functional groups that allow further chemical modifications. The compound is also employed in the development of specialty polymers and as a building block in organic synthesis, particularly in reactions requiring halogenated aromatic structures with controlled substitution patterns. Its hydroxy and carboxylic acid groups enable esterification and condensation reactions, useful in creating complex organic frameworks.
