Chemical Structure
Description
The occurrence of 3-(2,3-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(2,3-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline (CAS 918875-08-8) is a high-purity analytical reference standard with the molecular formula C15H12Cl2N2 and a molecular weight of 291.18 g/mol.
3-(2,3-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline (C15H12Cl2N2) 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 3-(2,3-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline 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.
