    2,2'-Dihydroxy-4,4'-Dimethoxybenzophenone

    (131-54-4)
    This product is a benzophenone ultraviolet absorber. Ultraviolet absorber is currently the most commonly used light stabilizer. This is a type of ultraviolet light that can strongly and selectively absorb high-energy ultraviolet light and convert energy to release or consume energy in the form of heat or harmless low-energy radiation Of the substance. Benzophenone containing an ortho-hydroxy group only absorbs ultraviolet light below 380nm and hardly absorbs visible light. This 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 visible light, making the product slightly yellow. Oral LD50 for rats is 3000mg/kg. Used as UV absorber

    UV Absorbers are currently the most widely used type of light stabilizers, which can absorb the ultraviolet light in sunlight and fluorescent light sources without changing themselves. According to its structure, it can be divided into salicylates, benzophenones, benzotriazoles, substituted acrylonitriles, triazines, etc. The most widely used in industry are benzophenones and benzotriazoles class. "UV Absorbers" on Echemi mainly supplies raw materials for UV Absorbers.
