Chemical Structure
Description
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.
2,2,2-Trifluoro-1,1-ethanediol 33953-86-5 T3279 Trifluoroacetaldehyde Monohydrate (CAS 33953-86-5) is a high-purity analytical reference standard with the molecular formula C2HF3OH2O and a molecular weight of 116.04 g/mol.
The molecular framework of 2,2,2-Trifluoro-1,1-ethanediol 33953-86-5 T3279 Trifluoroacetaldehyde Monohydrate (C2HF3OH2O) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
