Compared with other compounds in its class, the molecular weight of 442.12 g/mol gives 2-(3,4-Dichlorostyryl)-1-methylquinolin-1-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(3,4-Dichlorostyryl)-1-methylquinolin-1-ium iodide (CAS 110357-13-6), molecular formula C18H14Cl2NI and molecular weight 442.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution, 2-(3,4-Dichlorostyryl)-1-methylquinolin-1-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
