Chemical Structure
Description
3,4-Dichloro-N-(1-(3-methoxybenzyl)-5,6-dimethyl-1H-benzo[d]imidazol-4-yl)benzenesulfonamide (C23H21Cl2N3O3S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3,4-Dichloro-N-(1-(3-methoxybenzyl)-5,6-dimethyl-1H-benzo[d]imidazol-4-yl)benzenesulfonamide (CAS 338955-31-0) is a high-purity analytical reference standard with the molecular formula C23H21Cl2N3O3S and a molecular weight of 490.40 g/mol.
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.
