Used primarily as a chemical intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure allows for easy derivatization, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of esters and amides that serve as building blocks in drug development. Also utilized in the production of specialty polymers where controlled steric and electronic properties are required. Its methoxy and carboxylic acid functionalities enable participation in selective reactions, enhancing its utility in fine chemical manufacturing.
