Description
CATO supplies (3bR,9bS)-6-hydroxy-7-isopropyl-9b-methyl-3b,4,10,11-tetrahydrophenanthro[2,1-c]furan-1,5(3H,9bH)-dione (CAS 79548-61-1), a certified reference material (molecular formula C20H22O4, MW 326.39 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H22O4, (3bR,9bS)-6-hydroxy-7-isopropyl-9b-methyl-3b,4,10,11-tetrahydrophenanthro[2,1-c]furan-1,5(3H,9bH)-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 326.39 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).
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.
