2,3,4-Trihydroxybenzophenone Chemical Properties,Usage,Production
Uses
2,3,4-Trihydroxybenzophenone is used in manufacturing method of electrophotographic photosensitive member containing styrene acrylic resin particle and melamine formaldehyde resin particle.
Definition
ChEBI: 2,3,4-trihydroxbenzophenone is a benzenetriol that is benzophenone in which one of the phenyl groups is substituted by hydroxy groups at positions 2, 3, and 4. It is a redox mediator. It has a role as a quorum sensing inhibitor, an EC 1.14.18.1 (tyrosinase) inhibitor, a human urinary metabolite, a rat metabolite and a drug metabolite. It is a hydroxybenzophenone and a benzenetriol.
Preparation
Preparation by reaction of benzoic acid with pyrogallol,
in the presence of zinc chloride during 3 h at 145°;
in the presence of Amberlyst-15 (a strongly acid ion exchanger) in chlorobenzene during 10 h at 131–132° (60%);
in the presence of Amberlite IR-120 or Zeokarb 225 (cation exchange resins, sulfonic acid type) during 3 h at 160° (14%);
in the presence of boron trifluoride in ethyl ether at 0° (44%).
General Description
2,3,4-Trihydroxybenzophenone is a hydroxylated benzophenone UV filter and has been quantitated in sea water samples by dispersive liquid-liquid microextraction followed by GC-MS. Estrogenic activity of 2,3,4-trihydroxybenzophenone has been tested by yeast-two hybrid assay.
