Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports selective binding to enzyme active sites, making it valuable in drug discovery. Commonly employed in research settings to design molecules with antitumor and anti-inflammatory activities. Also utilized in the preparation of biologically active heterocyclic compounds due to its electron-withdrawing nitro and sulfonyl groups, which enhance reactivity in cross-coupling and substitution reactions.
