Chemical properties
yellow crystalline powder
The Uses of 2,4-Dihydroxybenzophenone
2,4-Dihydroxybenzophenone is an metabolite of Benzophenone (B204980), an compound used in the manufacturing of antihistamines, hypnotics and insecticides.
The Uses of 2,4-Dihydroxybenzophenone
Ultraviolet light absorber, especially in paints and plastics.
The Uses of 2,4-Dihydroxybenzophenone
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).
