| 2,4-Dihydroxybenzophenone Usage And Synthesis |
| Chemical Properties | yellow crystalline powder | | Uses | 2,4-Dihydroxybenzophenone is an metabolite of Benzophenone (B204980), an compound used in the manufacturing of antihistamines, hypnotics and insecticides. | | Uses | Ultraviolet light absorber, especially in paints and plastics. | | Uses | Novel mordent and disperse azo dyes were prepared by the coupling of various diazo solutions of aromatic amines with 2, 4-dihydroxybenzophenone. The ultraviolet absorbing monomers were synthesized by reaction of 2, 4-dihydroxybenzophenone with glycidyl acrylate and glycidyl methacrylate. Two new polymerizable stabilizers, 4-benzoyl-2-(α-piperidino-2-chlorobenzyl)-3-hydroxyphenyl acrylate (BPBHA) and corresponding methacrylate (BPBHMA), were synthesized and characterized from 2,4-Dihydroxybenzophenone. a polymerizable UV-stabilizer, 2-hydroxy-4-(3-methacryloxy-2-hydroxylpropoxy) benzophenone (BPMA), was synthesized using 2, 4-dihydroxybenzophenone (UV-0) and glycidyl methacrylate (GMA). | | Preparation | Obtained by condensation of benzanilide with resorcinol in the presence of zinc chloride and phosphorous oxychloride at 130–140° for 1 h (25%). | | Contact allergens | BZP-1 is used, for example, in paints, plastics, and nail
varnishes. | | Safety Profile | Poison by intravenous
and intraperitoneal routes. Mildly toxic by
ingestion. An eye irritant. When heated to
decomposition it emits acrid smoke and
irritating fumes. | | Purification Methods | Recrystallise it from MeOH. [Beilstein 8 IV 2442.] |
