3-(2,4-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline (CAS 918875-07-7), molecular formula C15H12Cl2N2 and molecular weight 291.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(2,4-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline (C15H12Cl2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
