Chemical Structure
Description
The molecular framework of 2-((N-(5-(Benzyloxy)-2,4-dichlorophenyl)-4-methylphenyl)sulfonamido)-N,N-dimethylacetamide (C24H24Cl2N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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 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).
2-((N-(5-(Benzyloxy)-2,4-dichlorophenyl)-4-methylphenyl)sulfonamido)-N,N-dimethylacetamide (CAS 338967-32-1), molecular formula C24H24Cl2N2O4S and molecular weight 507.43 g/mol, is a CATO reference standard with documented purity and traceability.
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.
