Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tris(2,2-difluoroethyl) phosphate (CAS 358-64-5) is a high-purity analytical reference standard with the molecular formula C6H9F6O4P and a molecular weight of 290.10 g/mol.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Tris(2,2-difluoroethyl) phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.10 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.
As a certified reference material (CRM), Tris(2,2-difluoroethyl) phosphate 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.
