Chemical Structure
Description
As a certified reference material (CRM), Ethyl (4-fluorophenyl)(hydroxy(pyridin-3-yl)methyl)phosphinate 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.
Ethyl (4-fluorophenyl)(hydroxy(pyridin-3-yl)methyl)phosphinate (CAS 69112-28-3) is a high-purity analytical reference standard with the molecular formula C14H15FNO3P and a molecular weight of 295.25 g/mol.
Ethyl (4-fluorophenyl)(hydroxy(pyridin-3-yl)methyl)phosphinate (C14H15FNO3P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
