Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly those targeting protein kinases involved in cancer cell proliferation. It serves as a building block in the development of small-molecule drugs due to its ability to bind selectively to ATP-binding sites in enzymes. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates for improved potency and metabolic stability. Its aromatic and hydrogen-bonding features make it valuable in designing compounds with enhanced target affinity and pharmacokinetic properties.
