Chemical Structure
Description
As a certified reference material (CRM), Flumethasone 21-Pivalate 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 21-Pivalate (CAS 2002-29-1) is a high-purity analytical reference standard with the molecular formula C27H36F2O6 and a molecular weight of 494.57 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, Flumethasone 21-Pivalate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 494.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
