The occurrence of (5bR,11bR)-1,2,5b,11b-Tetrahydro-2-(1-methylethenyl)-6H-furo[2′,3′:6,7]benzofuro[3,2-c][1]benzopyran-9-ol is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (5bR,11bR)-1,2,5b,11b-Tetrahydro-2-(1-methylethenyl)-6H-furo[2′,3′:6,7]benzofuro[3,2-c][1]benzopyran-9-ol (CAS 213912-46-0), a certified reference material (molecular formula C20H18O4, MW 322.35 g/mol) for analytical method development and quality control.
(5bR,11bR)-1,2,5b,11b-Tetrahydro-2-(1-methylethenyl)-6H-furo[2′,3′:6,7]benzofuro[3,2-c][1]benzopyran-9-ol (C20H18O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), (5bR,11bR)-1,2,5b,11b-Tetrahydro-2-(1-methylethenyl)-6H-furo[2′,3′:6,7]benzofuro[3,2-c][1]benzopyran-9-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.
