Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Diethyl 2-(trifluoromethyl)benzylphosphonate (CAS 99578-85-5), a certified reference material (molecular formula C12H16F3O3P, MW 296.22 g/mol) for analytical method development and quality control.
Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Diethyl 2-(trifluoromethyl)benzylphosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.22 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), Diethyl 2-(trifluoromethyl)benzylphosphonate 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.
