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-(2,2,2-trifluoroethyl)propanedioic acid (CAS 99783-24-1) is a high-purity analytical reference standard with the molecular formula C5H5F3O4 and a molecular weight of 186.09 g/mol.
Based on its molecular formula C5H5F3O4, 2-(2,2,2-trifluoroethyl)propanedioic acid contains a carbohydrate-derived structure, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 186.09 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.
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.
