1,1'-(Diphenyl)-3,3'-dimethyl-5-hydroxy[4,5']pyrazol is a pyrazole compound that is used in the manufacture of pharmaceuticals. It can be synthesized by reacting 2,2'-diamino-4,4'-diphenylpropane with 1,1-benzenediol and hydrochloric acid to produce 1,1'-(diphenyl)pyrazolone. This reaction produces an intermediate product that contains a hydrogen bond between the phenyl group and the hydroxyl group.
