Description
(6aS,7aR,8S,11aR,12aS)-5,6a,7,7a,8,9,11a,12a-Octahydro-4,8,11,11a,13-pentahydroxy-12a-methyl-5,9-dioxo-6,8-methano-6H-benzo[c]xanthene-10-carboxamide 1268494-44-5 (CAS 1268494-44-5) is a high-purity analytical reference standard with the molecular formula C20H17NO9 and a molecular weight of 415.35 g/mol.
(6aS,7aR,8S,11aR,12aS)-5,6a,7,7a,8,9,11a,12a-Octahydro-4,8,11,11a,13-pentahydroxy-12a-methyl-5,9-dioxo-6,8-methano-6H-benzo[c]xanthene-10-carboxamide 1268494-44-5 (C20H17NO9) contains a flavonoid core, an amide group, 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).
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.
CATO manufactures (6aS,7aR,8S,11aR,12aS)-5,6a,7,7a,8,9,11a,12a-Octahydro-4,8,11,11a,13-pentahydroxy-12a-methyl-5,9-dioxo-6,8-methano-6H-benzo[c]xanthene-10-carboxamide 1268494-44-5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
