Chemical Structure

2-(Phenylethynyl)-1,1'-biphenyl CAS 10271-65-5 chemical structure

Description

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 supplies 2-(Phenylethynyl)-1,1'-biphenyl (CAS 10271-65-5), a certified reference material (molecular formula C20H14, MW 254.33 g/mol) for analytical method development and quality control.

The molecular framework of 2-(Phenylethynyl)-1,1'-biphenyl (C20H14) is characterized by a polycyclic aromatic system. 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).

As a certified reference material (CRM), 2-(Phenylethynyl)-1,1'-biphenyl 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.
