Compared with other compounds in its class, the molecular weight of 256.14 g/mol gives 1,3-Bis(2,2,2-trifluoroethoxy)propan-2-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Bis(2,2,2-trifluoroethoxy)propan-2-ol (CAS 691-26-9) is a high-purity analytical reference standard with the molecular formula C7H10F6O3 and a molecular weight of 256.14 g/mol.
Based on its molecular formula C7H10F6O3, 1,3-Bis(2,2,2-trifluoroethoxy)propan-2-ol contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 256.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
