N2,N7-Bis(2,5-dimethylphenyl)-9H-fluorene-2,7-disulfonamide (CAS 321941-97-3), molecular formula C29H28N2O4S2 and molecular weight 532.67 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N2,N7-Bis(2,5-dimethylphenyl)-9H-fluorene-2,7-disulfonamide (C29H28N2O4S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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), N2,N7-Bis(2,5-dimethylphenyl)-9H-fluorene-2,7-disulfonamide 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.
