Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. It serves as a building block in organic reactions where selective bromo and chloro substitution enables further functionalization. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to construct complex aromatic systems. Also utilized in the preparation of dyes and specialty polymers due to its halogenated aromatic structure. Its carboxylic acid group allows for easy derivatization into esters, amides, or salts for improved solubility or reactivity in various industrial processes.
