Chemical Structure
Description
Diethyl (fluoromethyl)phosphonate (C5H12FO3P) contains a phosphonate group, 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.
Diethyl (fluoromethyl)phosphonate (CAS 96857-55-5) is a high-purity analytical reference standard with the molecular formula C5H12FO3P and a molecular weight of 170.12 g/mol.
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), Diethyl (fluoromethyl)phosphonate 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.
