Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain vasodilators and cardiovascular drugs. Its functional groups allow for selective esterification and amidation reactions, making it valuable in building complex organic molecules. Commonly employed in research settings for developing new bioactive compounds and in the preparation of prodrugs where controlled release is required. Also utilized in the design of specialty polymers due to its aromatic rigidity and multiple polar functional sites.
