5-Bromo-2-chloropyrimidine (CAS 32779-36-5) is a high-purity analytical reference standard with the molecular formula C4H2BrClN2 and a molecular weight of 193.43 g/mol.
Based on its molecular formula C4H2BrClN2, 5-Bromo-2-chloropyrimidine contains a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
