Chemical Structure
Description
21-O-Acetyl 6β-Hydroxy Dexamethasone (CAS 72559-77-4) is a high-purity analytical reference standard with the molecular formula C24H31FO7 and a molecular weight of 450.50 g/mol.
The molecular framework of 21-O-Acetyl 6β-Hydroxy Dexamethasone (C24H31FO7) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 21-O-Acetyl 6β-Hydroxy Dexamethasone 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.
