Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. It serves as a building block for psychoactive drugs and receptor ligands, especially those targeting serotonin, dopamine, and adrenergic receptors. Commonly found in research related to antidepressants, antipsychotics, and cognitive enhancers. Also utilized in the preparation of novel compounds for medicinal chemistry screening due to its structural flexibility and ability to cross the blood-brain barrier.
