Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure enables selective binding to enzyme targets, enhancing drug efficacy. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocyclic compounds with biological activity. Also utilized in research settings to develop new central nervous system (CNS) modulators due to its ability to cross the blood-brain barrier. Serves as a building block in the preparation of fluorescent probes for biochemical assays.
