Description
4-(1-cyclohexyl-4-(4-fluorophenyl)-1H-imidazol-5-yl)-2-pyrimidinamine 4-[1-cyclohexyl-4-(4-fluorophenyl)-1H-imidazol-5-yl]pyrimidin-2-amine 950980-98-0 CHEBI:87283 PF-670462 free base free base of PF-670462 (CAS 950980-98-0), molecular formula C19H20FN5 and molecular weight 337.39 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H20FN5, 4-(1-cyclohexyl-4-(4-fluorophenyl)-1H-imidazol-5-yl)-2-pyrimidinamine 4-[1-cyclohexyl-4-(4-fluorophenyl)-1H-imidazol-5-yl]pyrimidin-2-amine 950980-98-0 CHEBI:87283 PF-670462 free base free base of PF-670462 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 337.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 4-(1-cyclohexyl-4-(4-fluorophenyl)-1H-imidazol-5-yl)-2-pyrimidinamine 4-[1-cyclohexyl-4-(4-fluorophenyl)-1H-imidazol-5-yl]pyrimidin-2-amine 950980-98-0 CHEBI:87283 PF-670462 free base free base of PF-670462 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
