Chemical Structure
Description
(1S,2S,4S,5R)-2-((R)-Hydroxy(quinolin-4-yl)methyl)-1-(4-(trifluoromethyl)benzyl)-5-vinylquinuclidin-1-ium bromide (C27H28F3N2OBr) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(1S,2S,4S,5R)-2-((R)-Hydroxy(quinolin-4-yl)methyl)-1-(4-(trifluoromethyl)benzyl)-5-vinylquinuclidin-1-ium bromide (CAS 101311-12-0), molecular formula C27H28F3N2OBr and molecular weight 533.43 g/mol, is a CATO reference standard with documented purity and traceability.
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.
