Chemical Structure
Description
(2,6-Difluorophenyl)phosphonic acid diethyl ester (CAS 1250397-29-5), molecular formula C10H13F2O3P and molecular weight 250.18 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H13F2O3P, (2,6-Difluorophenyl)phosphonic acid diethyl ester contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (2,6-Difluorophenyl)phosphonic acid diethyl ester 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.
