Description
165074-00-0 2H-9,4a-(Epoxymethano)phenanthrene-5,6,10,12-tetrol,1,3,4,9,10,10a-hexahydro-1,1-dimethyl-7-(1-methylethyl)-,(4aR,9R,10R,10aS,11S)- (9CI) (CAS 165074-00-0), molecular formula C20H28O5 and molecular weight 348.43 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H28O5, 165074-00-0 2H-9,4a-(Epoxymethano)phenanthrene-5,6,10,12-tetrol,1,3,4,9,10,10a-hexahydro-1,1-dimethyl-7-(1-methylethyl)-,(4aR,9R,10R,10aS,11S)- (9CI) 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 348.43 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
