No carcinogenic, teratogenic, mutagenic effects. Rainbow trout LC50>12.5mg/L (96H). Acute oral LD50>5000mg/kg. |
| Use | sulfonylurea herbicides inhibit the synthesis of branched-chain amino acids, thereby inhibiting the cell division of plant growth ends, stop the growth of weeds to the loss of green necrosis. This product is a pre-Bud and post-Bud killing herbicide, which is suitable for the control of annual and perennial grass weeds and broad-leaved weeds in forest trees, or for the development of forest isolation zones, after logging and forest land clean-up, before reclamation, leisure non-cultivated land, weed control and irrigation of waste land along the road, such as Festuca arundinacea, goldenrod, millet, oil Cyperus papyrifera, Arabic sorghum, ragweed, etc. Dosage of 210 ~ 250g/h m2, can be conventional spraying, can also be sprayed by aircraft. It is not suitable for use in farmland. It is used to control annual and perennial grass weeds in non-cultivated land it belongs to urea sulfonate herbicide and is a broad-spectrum pre-and post-emergence herbicide, it is suitable for the control of annual and perennial grass weeds and broad-leaved weeds in forest trees. |
| production method | preparation of 2-amino -4, 6-dimethylpyrimidine starting from dicyandiamide and ammonium nitrate (or carbonate) A guanidine nitrate salt (or guanidine carbonate) was produced, and then 12.2g of guanidine nitrate, 10g of acetylacetone, 100ml of water and 8g of potassium carbonate were reacted at room temperature. After post-treatment by filtration, drying and the like, 7.4g of 2-amino -4, 6-dimethylpyrimidine was obtained in a yield of 60%. Preparation of methyl ortho-formate benzenesulfonyl isocyanate see method for preparation of metsulfuron-methyl. Synthesis of sulfuron-methyl 2-amino-4, 6-dimethylpyrimidine (4g) and methyl ortho-formate benzenesulfonyl isocyanate (7.8g) in acetonitrile (60ml) solvent, the reaction was stirred at room temperature for 16h and filtered to give white crystals in 91% yield. |
