1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium trifluoromethanesulfonate CAS 155862-98-9

Description

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.

CATO supplies 1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium trifluoromethanesulfonate (CAS 155862-98-9), a certified reference material (molecular formula C21H18N3O4CF3O3S, MW 525.45 g/mol) for analytical method development and quality control.

The molecular framework of 1-(2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)ethyl)-4-(5-(4-methoxyphenyl)oxazol-2-yl)pyridin-1-ium trifluoromethanesulfonate (C21H18N3O4CF3O3S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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).

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.
