Chemical Structure
Description
Triethyl 2-fluoro-2-phosphonoacetate (CAS 2356-16-3), molecular formula C8H16FO5P and molecular weight 242.18 g/mol, is a CATO reference standard with documented purity and traceability.
Triethyl 2-fluoro-2-phosphonoacetate (C8H16FO5P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
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.
