Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors. Its structure supports the formation of biologically active compounds targeting signaling pathways in cancer and inflammatory diseases. The tert-butyl carbamate group acts as a protecting group during peptide or heterocycle synthesis, allowing selective reactions at other functional sites. The methylsulfonyl moiety enhances electron-withdrawing properties, improving binding affinity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its stability and modularity in coupling reactions.
