Description

(1aS,1bS,6bS,7aS,8aS,11aS)-1b,3,6,6b,7,7a-Hexahydro-1b-methyl-10-(1-methylethyl)bisoxireno[4b,5:8a,9]phenanthro[1,2-c]furan-4,9(2H,11aH)-dione (CAS 216440-77-6), molecular formula C20H22O5 and molecular weight 342.39 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H22O5, (1aS,1bS,6bS,7aS,8aS,11aS)-1b,3,6,6b,7,7a-Hexahydro-1b-methyl-10-(1-methylethyl)bisoxireno[4b,5:8a,9]phenanthro[1,2-c]furan-4,9(2H,11aH)-dione 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 342.39 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (1aS,1bS,6bS,7aS,8aS,11aS)-1b,3,6,6b,7,7a-Hexahydro-1b-methyl-10-(1-methylethyl)bisoxireno[4b,5:8a,9]phenanthro[1,2-c]furan-4,9(2H,11aH)-dione 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.
