The occurrence of 2,5-Dichloro-N-{5,6-dimethyl-1-[(3-methylphenyl)methyl]-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Dichloro-N-{5,6-dimethyl-1-[(3-methylphenyl)methyl]-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide (CAS 338423-39-5) is a high-purity analytical reference standard with the molecular formula C23H21Cl2N3O2S and a molecular weight of 474.40 g/mol.
2,5-Dichloro-N-{5,6-dimethyl-1-[(3-methylphenyl)methyl]-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide (C23H21Cl2N3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 2,5-Dichloro-N-{5,6-dimethyl-1-[(3-methylphenyl)methyl]-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
