N-(2,4-dichlorophenyl)-2-((2-((4-methoxyphenyl)sulfonamido)phenyl)thio)acetamide CAS 477869-05-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,4-dichlorophenyl)-2-((2-((4-methoxyphenyl)sulfonamido)phenyl)thio)acetamide.

N-(2,4-dichlorophenyl)-2-((2-((4-methoxyphenyl)sulfonamido)phenyl)thio)acetamide (CAS 477869-05-9), molecular formula C21H18Cl2N2O4S2 and molecular weight 497.41 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C21H18Cl2N2O4S2, N-(2,4-dichlorophenyl)-2-((2-((4-methoxyphenyl)sulfonamido)phenyl)thio)acetamide contains a flavonoid 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 497.41 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.

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.
