Used primarily as a pharmaceutical intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of central nervous system (CNS) agents. It serves as a key building block in the production of analgesics and psychiatric medications due to its structural affinity for neurotransmitter receptors. Its derivatives are explored in research for treating depression, anxiety, and neuropathic pain. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving piperidine-based compounds.
