Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,5-Dichloro-N-{1-[(3-methoxyphenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide (CAS 338955-33-2), molecular formula C23H21Cl2N3O3S and molecular weight 490.40 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-Dichloro-N-{1-[(3-methoxyphenyl)methyl]-5,6-dimethyl-1H-1,3-benzodiazol-4-yl}benzene-1-sulfonamide (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.

As a certified reference material (CRM), 2,5-Dichloro-N-{1-[(3-methoxyphenyl)methyl]-5,6-dimethyl-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.
