4-n-Heptylbiphenyl CAS 59662-32-7 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 4-n-Heptylbiphenyl.

4-n-Heptylbiphenyl (CAS 59662-32-7), molecular formula C19H24 and molecular weight 252.39 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H24, 4-n-Heptylbiphenyl contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-n-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.
