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.
(1S,2R,4S,5R)-2-((S)-Hydroxy(quinolin-4-yl)methyl)-1-(2-oxo-2-((2-phenylpropan-2-yl)amino)ethyl)-5-vinylquinuclidin-1-ium bromide (CAS 2937392-02-2) is a high-purity analytical reference standard with the molecular formula C30H36N3O2Br and a molecular weight of 550.54 g/mol.
(1S,2R,4S,5R)-2-((S)-Hydroxy(quinolin-4-yl)methyl)-1-(2-oxo-2-((2-phenylpropan-2-yl)amino)ethyl)-5-vinylquinuclidin-1-ium bromide (C30H36N3O2Br) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
