Chemical Structure
Description
Based on its molecular formula C8H5F2IN2, 6-(1,1-Difluoro-2-iodoethyl)nicotinonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 294.04 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).
6-(1,1-Difluoro-2-iodoethyl)nicotinonitrile (CAS 2079953-93-6), molecular formula C8H5F2IN2 and molecular weight 294.04 g/mol, is a CATO reference standard with documented purity and traceability.
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.
