Used in the synthesis of pharmaceutical intermediates, 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. Also employed in the preparation of agrochemicals and functional materials where aromatic and nitrogen-containing systems enhance performance. Its carboxylic acid group allows for easy derivatization, enabling the creation of amides, esters, and other functional derivatives for structure-activity relationship studies.
