Description
As a certified reference material (CRM), Cyanidin 3-Xyloside 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.
Cyanidin 3-Xyloside (CAS 29761-24-8), molecular formula C20H19O10Cl and molecular weight 454.81 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H19O10Cl, Cyanidin 3-Xyloside contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 454.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
