Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the formation of biologically active molecules with high selectivity. Also employed in the preparation of functionalized heterocyclic compounds for use in medicinal chemistry and drug discovery research, targeting inflammatory and neurological disorders. The carboxylic acid group allows for easy derivatization, enabling the creation of amides and esters to fine-tune pharmacokinetic properties. Additionally, it serves as a building block in the design of novel organic materials, including organic semiconductors for electronics applications such as transistors and organic solar cells, due to its conjugated heterocyclic structure providing favorable electronic properties.
