Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where functionalized aromatic rings are required. Its carboxylic and ester groups allow for further chemical modifications, making it valuable in constructing complex organic molecules. Commonly employed in coupling reactions and heterocycle formation, it supports the creation of drug candidates in medicinal chemistry research. Also utilized in the preparation of specialty polymers and agrochemicals due to its reactivity and structural features.
