Description

(1S,4aR,5S,6S,6aR,9S,11aS,12S,14S)-1,5,6,14-Tetrahydroxy-12-methoxy-4,4-dimethyl-8-methylenedecahydro-1H-6,11b-(epoxymethano)-6a,9-methanocyclohepta[a]naphthalen-7(8H)-one (C21H30O7) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(1S,4aR,5S,6S,6aR,9S,11aS,12S,14S)-1,5,6,14-Tetrahydroxy-12-methoxy-4,4-dimethyl-8-methylenedecahydro-1H-6,11b-(epoxymethano)-6a,9-methanocyclohepta[a]naphthalen-7(8H)-one (CAS 155977-87-0) is a high-purity analytical reference standard with the molecular formula C21H30O7 and a molecular weight of 394.46 g/mol.

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), (1S,4aR,5S,6S,6aR,9S,11aS,12S,14S)-1,5,6,14-Tetrahydroxy-12-methoxy-4,4-dimethyl-8-methylenedecahydro-1H-6,11b-(epoxymethano)-6a,9-methanocyclohepta[a]naphthalen-7(8H)-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.
