Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2R,4S,5R)-1-(2-([1,1'-Biphenyl]-2-ylamino)-2-oxoethyl)-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide.
(1S,2R,4S,5R)-1-(2-([1,1'-Biphenyl]-2-ylamino)-2-oxoethyl)-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide (CAS 2798945-91-0), molecular formula C33H34N3O2Br and molecular weight 584.56 g/mol, is a CATO reference standard with documented purity and traceability.
(1S,2R,4S,5R)-1-(2-([1,1'-Biphenyl]-2-ylamino)-2-oxoethyl)-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide (C33H34N3O2Br) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
CATO manufactures (1S,2R,4S,5R)-1-(2-([1,1'-Biphenyl]-2-ylamino)-2-oxoethyl)-2-((S)-hydroxy(quinolin-4-yl)methyl)-5-vinylquinuclidin-1-ium bromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
