3-(2,5-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline CAS 918875-02-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2,5-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline.

3-(2,5-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline (CAS 918875-02-2), 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-(2,5-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. 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.

As a certified reference material (CRM), 3-(2,5-Dichlorophenyl)-5,6,7,8-tetrahydro-5,8-methanocinnoline 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.
