CATO supplies 6,7-dimethyl-8-(naphthalen-1-yl)-7,8-dihydro-6H-[1,3]dioxolo[4,5-g]chromen-6-ol (CAS 1005070-79-0), a certified reference material (molecular formula C22H20O4, MW 348.39 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H20O4, 6,7-dimethyl-8-(naphthalen-1-yl)-7,8-dihydro-6H-[1,3]dioxolo[4,5-g]chromen-6-ol 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 348.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 6,7-dimethyl-8-(naphthalen-1-yl)-7,8-dihydro-6H-[1,3]dioxolo[4,5-g]chromen-6-ol 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.
