Description
As a certified reference material (CRM), Reactive Yellow 86 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.
Reactive Yellow 86 (CAS 61951-86-8) is a high-purity analytical reference standard with the molecular formula C18H14Cl2N8O9S2Na and a molecular weight of 644.37 g/mol.
Reactive Yellow 86 (C18H14Cl2N8O9S2Na) contains a salt form, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
