Chemical Structure
Description
(16α)-9-Fluoro-16,17,21-trihydroxy-pregna-1,4-diene-3,11,20-trione (CAS 3107-69-5), molecular formula C21H25FO6 and molecular weight 392.42 g/mol, is a CATO reference standard with documented purity and traceability.
(16α)-9-Fluoro-16,17,21-trihydroxy-pregna-1,4-diene-3,11,20-trione (C21H25FO6) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (16α)-9-Fluoro-16,17,21-trihydroxy-pregna-1,4-diene-3,11,20-trione 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.
