Uses

2,2 '-dihydroxy-4, 4'-dimethoxybenzophenone is used as an ultraviolet absorber, especially in paints and plastics.
This product is a benzophenone ultraviolet absorber.  Ultraviolet absorber is the most commonly used light stabilizer at present.  It is a kind of substance that can strongly and selectively absorb high-energy ultraviolet light and carry out energy conversion, and release or consume energy in the form of heat energy or harmless low-energy radiation.  Benzophenone containing an ortho hydroxyl group only absorbs ultraviolet light below 380nm, and hardly absorbs visible light.  The product has strong absorption in the wavelength range of 270-380nm, and is suitable for polyvinyl chloride, acrylic resin, epoxy resin, phenolic resin, nitrocellulose and polyurethane.  But the product can absorb part of the visible light, making the product slightly yellow.  Oral LD50 to rats is 3000mg/kg.
