The occurrence of 2,4,6-Trichloronicotinonitrile is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4,6-Trichloronicotinonitrile (CAS 40381-91-7), molecular formula C6HCl3N2 and molecular weight 207.44 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6HCl3N2, 2,4,6-Trichloronicotinonitrile contains a nitrile group, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 207.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
