Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors. Shows potential in the development of anticancer agents due to its ability to interact with specific enzyme targets involved in cell signaling pathways. Also employed in the design of anti-inflammatory drugs, leveraging its structural features for enhanced binding to target proteins. Its carboxylic acid and nitro groups allow for further chemical modifications, making it valuable in medicinal chemistry for structure-activity relationship studies.
