Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting cancer-related enzymes such as PI3K and mTOR. Its structure supports high selectivity and binding affinity in small molecule drug candidates. Commonly employed in the development of antitumor agents due to its ability to modulate signaling pathways involved in cell proliferation and survival. Also utilized in structure-activity relationship (SAR) studies to optimize potency and metabolic stability in preclinical drug discovery programs.
