Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to form stable heterocyclic structures that interact with biological targets. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) targeting inflammatory diseases and neurological disorders. Its carboxylic acid functionality allows for easy derivatization, enabling the creation of amides, esters, and other functional groups important in drug design. Also utilized in agrochemical research for developing new crop protection agents.
