Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. It plays a role in the development of compounds that modulate signaling pathways involved in cell growth and proliferation. Its structure allows for selective binding to ATP sites in kinases, making it valuable in designing drugs for oncology and inflammatory diseases. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies to optimize potency and selectivity of drug candidates.
