Chemical Structure
Description
4-(4-Chlorophenyl)-6-(difluoromethyl)-2-hydrazinylpyrimidine (C11H9ClF2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine 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.
4-(4-Chlorophenyl)-6-(difluoromethyl)-2-hydrazinylpyrimidine (CAS 861408-89-1) is a high-purity analytical reference standard with the molecular formula C11H9ClF2N4 and a molecular weight of 270.67 g/mol.
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.
