3-Chloro-N-(4-chloro-2-((5-chloropyridin-2-yl)carbamoyl)-6-methoxyphenyl)-4-((2-(methylamino)-1H-imidazol-1-yl)methyl)thiophene-2-carboxamide (CAS 229336-92-9), molecular formula C23H19Cl3N6O3S and molecular weight 565.86 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C23H19Cl3N6O3S, 3-Chloro-N-(4-chloro-2-((5-chloropyridin-2-yl)carbamoyl)-6-methoxyphenyl)-4-((2-(methylamino)-1H-imidazol-1-yl)methyl)thiophene-2-carboxamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 565.86 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.
