Chemical Structure

Methyl 6-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-[(E)-({[(4-chlorophenyl)methoxy]amino}methylidene)amino]-4H,5H,6H,7H-thieno[2,3-c]pyridine-3-carboxylate CAS 321430-40-4 chemical structure

Description

The occurrence of Methyl 6-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-[(E)-({[(4-chlorophenyl)methoxy]amino}methylidene)amino]-4H,5H,6H,7H-thieno[2,3-c]pyridine-3-carboxylate is closely related to a steroid 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 Methyl 6-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-[(E)-({[(4-chlorophenyl)methoxy]amino}methylidene)amino]-4H,5H,6H,7H-thieno[2,3-c]pyridine-3-carboxylate (CAS 321430-40-4), a certified reference material (molecular formula C23H19Cl2F3N4O3S, MW 559.39 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Methyl 6-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-[(E)-({[(4-chlorophenyl)methoxy]amino}methylidene)amino]-4H,5H,6H,7H-thieno[2,3-c]pyridine-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 559.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
