Description
As a certified reference material (CRM), Flumethasone Methyl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Flumethasone Methyl (CAS CATO-C4X-19106) is a high-purity analytical reference standard with the molecular formula C22H28F2O5 and a molecular weight of 410.45 g/mol.
Flumethasone Methyl (C22H28F2O5) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
