yellow crystalline powder
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).
Ultraviolet light absorber, especially in paints and plastics.
2,4-Dihydroxybenzophenone is an metabolite of Benzophenone (B204980), an compound used in the manufacturing of antihistamines, hypnotics and insecticides.
ChEBI: 2,4-Dihydroxybenzophenone is a member of benzophenones.
Obtained by condensation of benzanilide with resorcinol in the presence of zinc chloride and phosphorous oxychloride at 130–140° for 1 h (25%).
BZP-1 is used, for example, in paints, plastics, and nail
varnishes.
Poison by intravenous
and intraperitoneal routes. Mildly toxic by
ingestion. An eye irritant. When heated to
decomposition it emits acrid smoke and
irritating fumes.
Recrystallise it from MeOH. [Beilstein 8 IV 2442.]
