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.
1-(2-(2,4-Dichlorophenyl)-2-oxoethyl)pyridin-1-ium iodide (CAS 246022-02-6), molecular formula C13H10Cl2NOI and molecular weight 394.03 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H10Cl2NOI, 1-(2-(2,4-Dichlorophenyl)-2-oxoethyl)pyridin-1-ium iodide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 394.03 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.
