CATO supplies (E)-1-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-N-((((2,4-dichlorobenzyl)oxy)imino)methyl)piperidine-4-carboxamide (CAS 338780-74-8), a certified reference material (molecular formula C20H18Cl3F3N4O2, MW 509.74 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H18Cl3F3N4O2, (E)-1-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)-N-((((2,4-dichlorobenzyl)oxy)imino)methyl)piperidine-4-carboxamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 509.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
