Chemical Structure
Description
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.
N-(4,5-Dimethoxy-2-(2-phenylacetyl)phenyl)-4-methylbenzenesulfonamide (CAS 886493-72-7), molecular formula C23H23NO5S and molecular weight 425.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(4,5-Dimethoxy-2-(2-phenylacetyl)phenyl)-4-methylbenzenesulfonamide (C23H23NO5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
