Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(9α,13α,14α)-4-Hydroxy-3,7-dimethoxy-7,8-didehydromorphinan-6-one (CAS 240131-71-9), molecular formula C18H21NO4 and molecular weight 315.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (9α,13α,14α)-4-Hydroxy-3,7-dimethoxy-7,8-didehydromorphinan-6-one (C18H21NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
CATO manufactures (9α,13α,14α)-4-Hydroxy-3,7-dimethoxy-7,8-didehydromorphinan-6-one 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.
