Chemical Structure
Description
CATO supplies Isosakuranin (CAS 491-69-0), a certified reference material (molecular formula C22H24O10, MW 448.42 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H24O10, Isosakuranin contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 448.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), Isosakuranin 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.
