Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5,5-trifluoropent-3-yn-1-ol.
5,5,5-trifluoropent-3-yn-1-ol (CAS 27611-20-7), molecular formula C5H5F3O and molecular weight 138.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H5F3O, 5,5,5-trifluoropent-3-yn-1-ol contains 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 138.09 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.
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.
