Used primarily in pharmaceutical research as an intermediate in the synthesis of biologically active compounds. It serves as a key building block in the development of kinase inhibitors, particularly those targeting cancer-related pathways. Its structure supports binding to specific enzyme active sites, making it valuable in optimizing drug candidates for improved potency and selectivity. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modulate pharmacokinetic properties such as solubility and metabolic stability.
