Chemical Structure
Description
Based on its molecular formula C20H18N2CF3O3S, Mono(2,2'-(ethyne-1,2-diyl)bis(1-(but-3-yn-1-yl)pyridin-1-ium)) mono(trifluoromethanesulfonate) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 435.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies Mono(2,2'-(ethyne-1,2-diyl)bis(1-(but-3-yn-1-yl)pyridin-1-ium)) mono(trifluoromethanesulfonate) (CAS 1137275-64-9), a certified reference material (molecular formula C20H18N2CF3O3S, MW 435.44 g/mol) for analytical method development and quality control.
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.
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.
