N-[(1E)-{[(2,4-dichlorophenyl)methoxy]imino}methyl]-2-(4-fluorophenoxy)-4-methoxypyridine-3-carboxamide CAS 341966-68-5 chemical structure

Description

The occurrence of N-[(1E)-{[(2,4-dichlorophenyl)methoxy]imino}methyl]-2-(4-fluorophenoxy)-4-methoxypyridine-3-carboxamide is closely related to a flavonoid core, an amide 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 N-[(1E)-{[(2,4-dichlorophenyl)methoxy]imino}methyl]-2-(4-fluorophenoxy)-4-methoxypyridine-3-carboxamide (CAS 341966-68-5), a certified reference material (molecular formula C21H16Cl2FN3O4, MW 464.27 g/mol) for analytical method development and quality control.

The molecular framework of N-[(1E)-{[(2,4-dichlorophenyl)methoxy]imino}methyl]-2-(4-fluorophenoxy)-4-methoxypyridine-3-carboxamide (C21H16Cl2FN3O4) is characterized by a flavonoid core, an amide 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. 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.
