Chemical Structure

(1S,2R,4S,5R)-2-((S)-Hydroxy(6-methoxyquinolin-4-yl)methyl)-1-(4-nitrobenzyl)-5-vinylquinuclidin-1-ium bromide CAS 518359-34-7 chemical structure

Description

The occurrence of (1S,2R,4S,5R)-2-((S)-Hydroxy(6-methoxyquinolin-4-yl)methyl)-1-(4-nitrobenzyl)-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.

(1S,2R,4S,5R)-2-((S)-Hydroxy(6-methoxyquinolin-4-yl)methyl)-1-(4-nitrobenzyl)-5-vinylquinuclidin-1-ium bromide (CAS 518359-34-7) is a high-purity analytical reference standard with the molecular formula C27H30N3O4Br and a molecular weight of 540.46 g/mol.

The molecular framework of (1S,2R,4S,5R)-2-((S)-Hydroxy(6-methoxyquinolin-4-yl)methyl)-1-(4-nitrobenzyl)-5-vinylquinuclidin-1-ium bromide (C27H30N3O4Br) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
