Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports the introduction of the sulfonimidoyl group, which enhances binding selectivity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modulate polarity, solubility, and steric profile. Also utilized in the preparation of protease inhibitors and CNS-targeted agents where controlled lipophilicity and hydrogen bonding are critical.
