Chemical Structure
Description
5-Aminoquinoline-6,8-disulfonic acid (CAS 856086-65-2) is a high-purity analytical reference standard with the molecular formula C9H8N2O6S2 and a molecular weight of 304.30 g/mol.
5-Aminoquinoline-6,8-disulfonic acid (C9H8N2O6S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5-Aminoquinoline-6,8-disulfonic acid 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.
