2,4-Dichloro-N-{5,6-dimethyl-1-[(3-methylphenyl)methyl]-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide CAS 338423-46-4

Description

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.

2,4-Dichloro-N-{5,6-dimethyl-1-[(3-methylphenyl)methyl]-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide (CAS 338423-46-4), molecular formula C23H21Cl2N3O2S and molecular weight 474.40 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,4-Dichloro-N-{5,6-dimethyl-1-[(3-methylphenyl)methyl]-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide (C23H21Cl2N3O2S) is characterized by a steroid 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).

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.
