CATO supplies 4,4''''-Difluoro-5''-(4'-fluoro-[1,1'-biphenyl]-4-yl)-1,1':4',1'':3'',1''':4''',1''''-quinquephenyl (CAS 372956-40-6), a certified reference material (molecular formula C42H27F3, MW 588.66 g/mol) for analytical method development and quality control.
The molecular framework of 4,4''''-Difluoro-5''-(4'-fluoro-[1,1'-biphenyl]-4-yl)-1,1':4',1'':3'',1''':4''',1''''-quinquephenyl (C42H27F3) is characterized by fluorine substitution, 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 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.
