4-Allyl-2-chloropyridine (CAS 219727-28-3) is a high-purity analytical reference standard with the molecular formula C8H8ClN and a molecular weight of 153.61 g/mol.
4-Allyl-2-chloropyridine (C8H8ClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
