Used as a key intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the preparation of active pharmaceutical ingredients (APIs) where its carboxylic acid groups allow for easy derivatization into esters, amides, or other functionalized compounds. Its methoxy-substituted aromatic structure provides electronic and steric properties beneficial in drug design, especially in compounds targeting central nervous system disorders or anti-inflammatory agents. Also employed in the development of polymers and coordination compounds due to its ability to act as a rigid, bifunctional building block in metal-organic frameworks (MOFs) and specialty resins.
