Used as an intermediate in the synthesis of targeted cancer therapies, particularly kinase inhibitors. Its structure allows selective binding to specific enzyme targets involved in tumor growth and signal transduction pathways. Commonly employed in research and development of pharmaceuticals for oncology, especially in designing inhibitors of cyclin-dependent kinases (CDKs) and other tyrosine kinases. Due to its functional groups and stability, it supports optimization of drug potency and pharmacokinetic properties during preclinical development.
