Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the preparation of herbicides and plant growth regulators. Its iodo and carboxylic acid functional groups allow for coupling reactions and derivatization in organic synthesis. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to build complex aromatic structures. Also utilized in the development of fine chemicals where selective substitution on the aromatic ring is required. Its dimethoxy substitution pattern enhances solubility and directs further electrophilic substitution in specific positions during multi-step syntheses.
