Description
As a certified reference material (CRM), (4aR,8aR)-2-Phenyl-4,4a-dihydropyrano[3,2-d][1,3]dioxin-8(8aH)-one 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.
(4aR,8aR)-2-Phenyl-4,4a-dihydropyrano[3,2-d][1,3]dioxin-8(8aH)-one (CAS 23346-01-2) is a high-purity analytical reference standard with the molecular formula C13H12O4 and a molecular weight of 232.23 g/mol.
(4aR,8aR)-2-Phenyl-4,4a-dihydropyrano[3,2-d][1,3]dioxin-8(8aH)-one (C13H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
