Molecular formula: C9H17N5S

Structural formula:

Molecular weight: 227.33

CAS No. : 834-12-8

Physical and chemical properties:

White crystalline solid. m.p. 80～84℃ (recrystallized in petroleum ether), density 1.19g/m3, vapor pressure 1.12×10^-4Pa. The solubility is: acetone 500g/ChemicalbookL, methanol 450g/L, toluene 400g/L, water 18.5mg/L. It is stable in slightly acidic or slightly alkaline medium, and easily hydrolyzed in strong acid or strong alkaline medium. Non-flammable and non-corrosive.

Usage：

Selective systemic and conductive herbicide. It is a typical photosynthesis inhibitor. Used to control annual weeds in sugarcane, citrus, corn, soybean, potato, peas, and carrot fields. High doses can control certain perennial weeds, as well as aquatic weeds. For spring sugarcane field, use 80% wettable powder 1.95～3kg/hm2 (active ingredient 1.56～2.4kg), spray 600～750kg of water on stems and leaves. Used in autumn Chemicalbook sugarcane field, use 80% wettable powder 1.05-1.95kg/hm2 (active ingredient 0.84-1.56kg), spray 600-750kg of water at the three-leaf stage of weeds. Other crops can be used for soil treatment before seedling after sowing or stem and leaf treatment after seedling. At low concentrations, Ammiejing can promote plant growth, stimulate the growth of sprouts and roots, increase leaf area, thicken stems, etc. But at high concentrations it will have a strong inhibitory effect on plants.
