The molecular framework of (S)-12b-Methyl-1H-tetrapheno[5,4-bc]furan-3,6,8,11(2H,12bH)-tetraone (C21H23ClN6O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(S)-12b-Methyl-1H-tetrapheno[5,4-bc]furan-3,6,8,11(2H,12bH)-tetraone (CAS 86690-14-4), molecular formula C21H23ClN6O and molecular weight 410.90 g/mol, is a CATO reference standard with documented purity and traceability.
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.
