4,4'-Dimethylbiphenyl is used in the preparation of biphenyl-4,4’-dicarboxylic acid, which acts as a monomer utilized in the synthesis of linear long chain polymer through polycondensation reaction. It is used to prepare 4-(4'-methylphenyl)benzaldehyde by selective photoxygenation reaction using 9-phenyl-10-methylacridinium perchlorate as a catalyst under visible light irradiation.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
