RT null T1 Diflubenzuron: Health and Safety Guide 99 A1 United Nations Environment Programme, A1 World Health Organization, A1 International Labour Organisation, K1 health K1 toxic substance K1 health hazard K1 waste disposal SN 92 4 151099 4 YR 1995 FD 1995 LK https://wedocs.unep.org/handle/20.500.11822/29649 UL https://wedocs.unep.org/handle/20.500.11822/29649 NO Diflubenzuron is an odourless, white, crystalline solid. It is almost insoluble in water and poorly soluble in apolar organic solvents. In polar to very polar solvents, the solubility is moderate to good, e.g., in acetone 6.5 g/litre at 20 C. Diflubenzuron is highly soluble in N-methylpyrolidone (200 g/litre), dimethylsulfoxide, and dimethylformamide (both 120 g/litre). DS UN Environment Document Repository RD Sep 22, 2026
