CATO supplies 4'',5''-Bis(4'-formyl-[1,1'-biphenyl]-4-yl)-[1,1':4',1'':2'',1''':4''',1''''-quinquephenyl]-4,4''''-dicarbaldehyde (CAS 2376339-70-5), a certified reference material (molecular formula C58H38O4, MW 798.92 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 4'',5''-Bis(4'-formyl-[1,1'-biphenyl]-4-yl)-[1,1':4',1'':2'',1''':4''',1''''-quinquephenyl]-4,4''''-dicarbaldehyde is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 798.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
