Chemical Structure
Description
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.
(1S,2R,4S,5R)-1-(2-(Benzhydrylamino)-2-oxoethyl)-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide (CAS 2937391-99-4), molecular formula C34H36N3O2Br and molecular weight 598.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1S,2R,4S,5R)-1-(2-(Benzhydrylamino)-2-oxoethyl)-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide (C34H36N3O2Br) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
