Chemical Properties
yellow crystalline powder
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).
Uses
Ultraviolet light absorber, especially in paints and plastics.
Uses
2,4-Dihydroxybenzophenone is an metabolite of Benzophenone (B204980), an compound used in the manufacturing of antihistamines, hypnotics and insecticides.
Definition
ChEBI: 2,4-Dihydroxybenzophenone is a member of benzophenones.
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.]
