4-Phenylphenol is an organic compound with the formula C₆H₅−C₆H₄OH. It is one of three isomers of hydroxybiphenyl.^[1]

Production

4-Phenylphenol is produced as a byproduct in the conversion of chlorobenzene to phenol with base. It can also be obtain by sulfonation of biphenyl to give 4-biphenylsulfonic acid, which can be hydrolyzed.^[1]

Of academic interest, 4-phenylphenol can be obtained from the Suzuki coupling of phenylboronic acid with 4-iodophenol in the presence of 10% palladium on carbon and potassium carbonate.^[2][3]

Properties

4-Phenylphenol is a flammable, difficult to ignite, white, scaly solid with a phenol-like odor that is very slightly soluble in water.^[4]
