Used primarily in pharmaceutical research as a chiral building block for the synthesis of neuroactive compounds. Its structural similarity to nicotinic receptor ligands makes it valuable in developing treatments for neurological disorders such as depression, schizophrenia, and neuropathic pain. Also employed in the preparation of catalysts for asymmetric synthesis, where the (S)-configuration plays a critical role in enantioselectivity. Commonly found in early-stage drug discovery for optimizing bioavailability and receptor binding affinity.
