Chemical Structure
Description
2-[(E)-2-{[1,1'-biphenyl]-4-yl}ethenyl]-1-methylpyridin-1-ium iodide (C20H18NI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-[(E)-2-{[1,1'-biphenyl]-4-yl}ethenyl]-1-methylpyridin-1-ium iodide (CAS 1025707-65-6), molecular formula C20H18NI and molecular weight 399.27 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.
