Description
As a certified reference material (CRM), Sunset Yellow (E110) D4 (phenyl D4) 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.
Sunset Yellow (E110) D4 (phenyl D4) (CAS 2259674-84-3) is a high-purity analytical reference standard with the molecular formula C16H22D4N2O7S2Na and a molecular weight of 449.52 g/mol.
The molecular framework of Sunset Yellow (E110) D4 (phenyl D4) (C16H22D4N2O7S2Na) is characterized by deuterium isotope labeling, a flavonoid 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.
