5",5"'-Bis(4'-formyl-[1,1'-biphenyl]-4-yl)-2",2"',4",4"',6",6"'-hexamethyl-[1,1':4',1":3",1"':3"',1"":4"",1""'-sexiphenyl]-4,4""'-dicarbaldehyde (CAS 868046-60-0), molecular formula C70H54O4 and molecular weight 959.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C70H54O4, 5",5"'-Bis(4'-formyl-[1,1'-biphenyl]-4-yl)-2",2"',4",4"',6",6"'-hexamethyl-[1,1':4',1":3",1"':3"',1"":4"",1""'-sexiphenyl]-4,4""'-dicarbaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 959.18 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).
