3.CAS ON:131-56-6

4.Nature:pale yellow or white needle-like crystalline powder

5.purposes:UV absorber used by the Commodities derivatives of 2-hydroxy-4-methoxy - benzophenone (UV-9), 2-hydroxy-4-octyloxybenzophenone benzophenone (UV-531) Benzophenone and its he single-hydroxy-, double-hydroxy-, 3-hydroxy and four hydroxy compounds such application is the most widely absorption optical stabilizer. Absorbing 290-400 nm UV, and the majority of synthetic resin with a good compatibility, are widely used polymer materials. 2,4-Dihydroxybenzophenone applicable to PVC, polystyrene, epoxy resin, cellulose resins, unsaturated polyester, paints and synthetic rubber. The maximum absorption wavelength range 280-340 nm and the general amount of 0.1-1%. However, the goods-stabilizing effect is not prominent. The goods on the rat oral LD50 ash 8,600 mg / kg in mice to 2336 mg / kg.
