(E)-4-(2-((4-Methoxyphenyl)sulfonamido)styryl)pyridine 1-oxide CAS 173529-10-7

Description

The occurrence of (E)-4-(2-((4-Methoxyphenyl)sulfonamido)styryl)pyridine 1-oxide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-4-(2-((4-Methoxyphenyl)sulfonamido)styryl)pyridine 1-oxide (CAS 173529-10-7), a certified reference material (molecular formula C20H18N2O4S, MW 382.43 g/mol) for analytical method development and quality control.

The molecular framework of (E)-4-(2-((4-Methoxyphenyl)sulfonamido)styryl)pyridine 1-oxide (C20H18N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.

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.
