Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 380.30 g/mol gives Tetraisopropyl (difluoromethylene)bis(phosphonate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetraisopropyl (difluoromethylene)bis(phosphonate) (CAS 78715-59-0) is a high-purity analytical reference standard with the molecular formula C13H28F2O6P2 and a molecular weight of 380.30 g/mol.
Tetraisopropyl (difluoromethylene)bis(phosphonate) (C13H28F2O6P2) contains a phosphate ester 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
