Description
As a certified reference material (CRM), Sodium 3-ethoxy-2-fluoro-3-oxoprop-1-en-1-olate 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.
Sodium 3-ethoxy-2-fluoro-3-oxoprop-1-en-1-olate (CAS 1652-39-7), molecular formula C5H6FO3Na and molecular weight 156.09 g/mol, is a CATO reference standard with documented purity and traceability.
Sodium 3-ethoxy-2-fluoro-3-oxoprop-1-en-1-olate (C5H6FO3Na) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
