Compared with other compounds in its class, the molecular weight of 275.13 g/mol gives 4,6-Dichloro-2-phenyl-quinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,6-Dichloro-2-phenyl-quinazoline (CAS 54665-93-9), molecular formula C14H8Cl2N2 and molecular weight 275.13 g/mol, is a CATO reference standard with documented purity and traceability.
4,6-Dichloro-2-phenyl-quinazoline (C14H8Cl2N2) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 4,6-Dichloro-2-phenyl-quinazoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
