(1S,2R,4S,5R)-1-Benzyl-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide CAS 85653-34-5 chemical structure

Description

The occurrence of (1S,2R,4S,5R)-1-Benzyl-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (1S,2R,4S,5R)-1-Benzyl-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide (CAS 85653-34-5), a certified reference material (molecular formula C26H29N2OBr, MW 465.44 g/mol) for analytical method development and quality control.

The molecular framework of (1S,2R,4S,5R)-1-Benzyl-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide (C26H29N2OBr) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
