The occurrence of Ethyl 2-[(dipropoxyphosphoryl)oxy]-3,3,3-trifluoropropanoate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 2-[(dipropoxyphosphoryl)oxy]-3,3,3-trifluoropropanoate (CAS 256333-00-3), molecular formula C11H20F3O6P and molecular weight 336.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 2-[(dipropoxyphosphoryl)oxy]-3,3,3-trifluoropropanoate (C11H20F3O6P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 336.24 g/mol, it falls into the moderately-high-molecular-weight range. 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.
