Metabolite of benzophenone. | [Definition]
ChEBI: 4-Hydroxybenzophenone is a member of benzophenones. | [Preparation]
Preparation by condensation of benzotrichloride,
? with phenol in the presence of aluminium chloride in carbon disulfide at 0° (90%) or in the presence of zinc oxide in a water bath;
? with p-bromophenol in 30% sodium hydroxide solution at 80–85° (81%). There is substitution of the bromine atom by the benzoyl group. | [Synthesis Reference(s)]
