4-Hydroxybenzophenone Chemical Properties,Usage,Production
Chemical Properties
white to beige fine crystalline powder
Uses
4-Hydroxybenzophenone is used in the field of organic synthesis. It is used as pharmaceutical intermediate of clomifene citrate.
Uses
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.
