Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It exhibits utility in medicinal chemistry due to its ability to selectively bind to ATP-binding sites in protein kinases, contributing to the modulation of cellular signaling pathways. Also employed in research settings for structure-activity relationship (SAR) studies aimed at optimizing antitumor and anti-inflammatory agents. Its nitro and chloro functional groups allow for further chemical modifications, enhancing its versatility in drug discovery.
