Chemical Structure

2',5'-Di((E)-styryl)-1,1':4',1''-terphenyl CAS 842170-20-1 chemical structure

Description

The molecular framework of 2',5'-Di((E)-styryl)-1,1':4',1''-terphenyl (C34H26) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 2',5'-Di((E)-styryl)-1,1':4',1''-terphenyl (CAS 842170-20-1), a certified reference material (molecular formula C34H26, MW 434.57 g/mol) for analytical method development and quality control.

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.
