4-Phenylphenol may be used in the following studies:
- As a reactant in the synthesis of new azobenzene sulfonic acid dopants by diazotized coupling reaction with sulphanilic acid diazonium salt.
- As a starting material in the synthesis of 2,6-poly(4-phenylphenol).
- As a ligand in the synthesis of aluminum (III) bis(2-methyl-8-quninolinato)-4-phenylphenolate (BAlq).
