N-Desmethyl Pirenzepine

N-Desmethyl Pirenzepine is a tropane alkaloid derivative featuring a 1-azabicyclo[2.2.2]octane core fused to a benzene ring, with a piperidine side chain lacking the N-methyl substituent present in pirenzepine. The structure includes an ester-linked 4-hydroxybenzoyl moiety and a quaternary ammonium center. This compound arises via N-demethylation of the parent drug, altering its anticholinergic activity. It serves as a critical HPLC reference standard for quantifying pirenzepine-related impurities in pharmaceutical formulations.
