Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
Ethyl 2-(diethoxyphosphoryl)-3-(4-methoxyphenyl)propanoate (CAS 35085-33-7), molecular formula C12H10Cl2F4O2 and molecular weight 333.11 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-(diethoxyphosphoryl)-3-(4-methoxyphenyl)propanoate (C12H10Cl2F4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
