Compared with other compounds in its class, the molecular weight of 366.84 g/mol gives 2-Chloro-4-[4-(1-naphthyl)phenyl]quinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-4-[4-(1-naphthyl)phenyl]quinazoline (CAS 1373265-62-3), molecular formula C24H15ClN2 and molecular weight 366.84 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-4-[4-(1-naphthyl)phenyl]quinazoline (C24H15ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
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), 2-Chloro-4-[4-(1-naphthyl)phenyl]quinazoline 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.
