5-((Trifluoromethyl)thio)pyridin-2-amine (CAS 1153767-57-7), molecular formula C6H5F3N2S and molecular weight 194.18 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H5F3N2S, 5-((Trifluoromethyl)thio)pyridin-2-amine contains a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 194.18 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.
