Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Bis(6-Bromoquinoline)sulfate (CAS 1072944-78-5), molecular formula C9H6BrNH2O4S and molecular weight 306.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, Bis(6-Bromoquinoline)sulfate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Bis(6-Bromoquinoline)sulfate 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.
