Description
As a certified reference material (CRM), 5,7-dihydroxy-2-phenyl-4H-chromen-4-one-8-d 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.
5,7-dihydroxy-2-phenyl-4H-chromen-4-one-8-d (CAS CATO-C3D-262393) is a high-purity analytical reference standard with the molecular formula C15H9DO4 and a molecular weight of 255.24 g/mol.
Owing to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage, 5,7-dihydroxy-2-phenyl-4H-chromen-4-one-8-d is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.24 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
