4-Hydroxybenzophenone Usage And Synthesis
Chemical Propertieswhite to beige fine crystalline powder
UsesMetabolite of benzophenone.
Uses4-Hydroxybenzophenone is used in the field of organic synthesis. It is used as pharmaceutical intermediate of clomifene citrate.
PreparationPreparation 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.

DefinitionChEBI: 4-Hydroxybenzophenone is a member of benzophenones.
