Chemical Structure

Direct Blue 6 CAS 2602-46-2 chemical structure

Description

Direct Blue 6 (CAS 2602-46-2), molecular formula C32H20N6O14S4Na and molecular weight 863.77 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Direct Blue 6 (C32H20N6O14S4Na) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Direct Blue 6 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.
