Used as an 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 enhance binding affinity to target proteins. Also employed in the preparation of agrochemicals and functional materials where nitro-aromatic systems contribute to electronic or photochemical properties. Its carboxylic acid group allows for easy derivatization, enabling conjugation into larger molecules for structure-activity relationship studies.
