Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of kinase inhibitors. It serves as a building block for drug candidates targeting inflammatory diseases and certain cancers due to its ability to modulate enzyme activity. Its structure supports binding to specific protein targets, enhancing selectivity and potency in therapeutic agents. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug efficacy and metabolic stability.
