(E)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2-(3,4-dimethoxyphenyl)ethene-1-sulfonamide CAS 478080-67-0 chemical structure

Description

The occurrence of (E)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2-(3,4-dimethoxyphenyl)ethene-1-sulfonamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2-(3,4-dimethoxyphenyl)ethene-1-sulfonamide (CAS 478080-67-0), a certified reference material (molecular formula C18H19ClF3N3O4S, MW 465.87 g/mol) for analytical method development and quality control.

The molecular framework of (E)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2-(3,4-dimethoxyphenyl)ethene-1-sulfonamide (C18H19ClF3N3O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), (E)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2-(3,4-dimethoxyphenyl)ethene-1-sulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
