Chemical Structure

4-Cyano-4'-heptylbiphenyl CAS 41122-71-8 chemical structure

Description

The molecular framework of 4-Cyano-4'-heptylbiphenyl (C20H35N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

4-Cyano-4'-heptylbiphenyl (CAS 41122-71-8) is a high-purity analytical reference standard with the molecular formula C20H35N and a molecular weight of 289.50 g/mol.

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), 4-Cyano-4'-heptylbiphenyl 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.
