Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and anti-inflammatory agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for designing bioactive molecules. It is also employed in the preparation of agrochemicals and specialty materials where heterocyclic frameworks are required. The carboxylic acid group enables coupling reactions to form amides or esters, facilitating the creation of compound libraries for drug discovery.
