Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting tyrosine kinases involved in cancer cell proliferation. Its structure enables selective binding to ATP sites in enzymes, making it valuable in developing targeted therapies for oncology. Commonly employed in medicinal chemistry for optimizing drug candidates due to its metabolic stability and favorable binding interactions. Also utilized in structure-activity relationship (SAR) studies to enhance potency and selectivity of anti-cancer compounds.
