Used as a key intermediate in the synthesis of pharmaceuticals, 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 hydrogen bonds and interact with biological targets. Also employed in the preparation of agrochemicals and functional materials where nitrogen-containing heterocycles enhance activity and stability. Its carboxylic acid group allows for easy derivatization, enabling the creation of amides, esters, and other functional derivatives for structure-activity relationship studies.
