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 amide bonds and participate in cross-coupling reactions. Also employed in the preparation of fluorescent probes and sensors owing to its electron-withdrawing nitro group and aromatic framework. Its structural features make it valuable in structure-activity relationship (SAR) studies for optimizing drug candidates.
