CAS 25162-00-9 For Pharmaceutical

(R)-3-(1-Methyl-2-pyrrolidinyl)pyridine​ CAS 25162-00-9 is the dextrorotatory (R)-enantiomer of nicotine, the principal alkaloid found in plants of the Nicotianagenus. Its structure consists of a pyridine ring linked to an N-methylpyrrolidine ring, with a stereogenic center at the 2'-position of the pyrrolidine ring.This compound is enantiomerically pure, natural-configuration (R)-(−)-Nicotine. Its value is defined by its specific, high-affinity interaction with nicotinic acetylcholine receptors (nAChRs), making it the gold-standard ligand and active ingredient​ for research and precision applications where stereochemical purity is non-negotiable for biological activity and regulatory compliance.
