Used as a key intermediate in the synthesis of pharmaceutical agents, particularly kinase inhibitors. It plays a role in the development of targeted cancer therapies due to its ability to selectively bind to specific enzyme active sites involved in tumor growth. Its structure supports optimization of potency and selectivity in drug candidates, especially in treatments for solid tumors and hematological malignancies. Also utilized in research settings for structure-activity relationship (SAR) studies to improve metabolic stability and bioavailability of new drug molecules.
