Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for targeted cancer therapies. Its structure allows for selective modification, making it valuable in creating compounds with high binding affinity to specific enzyme active sites. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles found in bioactive molecules. Also utilized in research settings to develop new central nervous system (CNS) active drugs due to its ability to cross the blood-brain barrier.
