Chemical Structure
Description
2,2-Difluoro-1-(4-methoxyphenyl)ethyl diethyl phosphate (CAS 191014-14-9) is a high-purity analytical reference standard with the molecular formula C13H19F2O5P and a molecular weight of 324.26 g/mol.
The molecular framework of 2,2-Difluoro-1-(4-methoxyphenyl)ethyl diethyl phosphate (C13H19F2O5P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 2,2-Difluoro-1-(4-methoxyphenyl)ethyl diethyl 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.
