4,6-Dichloro-2-(pyridin-4-yl)pyrimidine (CAS 89508-48-5) is a high-purity analytical reference standard with the molecular formula C9H5Cl2N3 and a molecular weight of 226.06 g/mol.
The molecular framework of 4,6-Dichloro-2-(pyridin-4-yl)pyrimidine (C9H5Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
