Description

Compared with other compounds in its class, the molecular weight of 271.08 g/mol gives 3,4-Dichloro-2-nitrobenzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Dichloro-2-nitrobenzenesulfonamide (CAS 1806367-57-6), molecular formula C6H4Cl2N2O4S and molecular weight 271.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Dichloro-2-nitrobenzenesulfonamide (C6H4Cl2N2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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).

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

As a certified reference material (CRM), 3,4-Dichloro-2-nitrobenzenesulfonamide 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.
