| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| toxicity | Acute oral LD50> 5000mg/kg in both rats and mice. Rats were fed for 3 months with a non-active dose of 5000mg/kg feed, 5000mg/kg feed for mice, and 3000mg/kg feed for dogs. There was no teratogenic and mutagenic effect under the experimental conditions. Quail and wild duck acute oral LD50>2250mg/kg. LC50>600mg/L (96h) for sunfish, rainbow trout and blue strontium fish. No irritation to the skin, moderate to the eyes, temporary stimulation. Low toxicity to bees. |
| Use | sulfonylurea herbicides are inhibitors of branched-chain amino acid synthesis and inhibit acetolactate synthase. For the control of weeds in rape field, with good selectivity. It has a good control effect on manext, Cardamine, Humulus, pig, etc. The dosage is 0.3~0.6g/100, which can be used before and after sowing; it is safe for later crops such as rice, cotton and wheat. Should not be used in rice, cotton, corn, melon, bean crop fields. A sulfonylurea herbicide for rapeseed field A broad-spectrum herbicide for rapeseed field, capable of controlling broad-leaved weeds in rapeseed field, at the same time, it also has obvious inhibitory effect on grass weeds |
| production method | preparation of 2-amino-4-methylamino-6-ethoxys-triazobenzene 57g of cyanuric chloride was dissolved in 800ml of acetone, cooling to -10 °c, ammonia 11g, reaction 30min; Drop add methylamine aqueous solution 84G, Reaction 3H at 30 °c; after work-up, 46.5g of 2-amino-4-methylamino-6-chloro-s-triazobenzene with a melting point of> 230 °c were obtained. Then it was refluxed and reacted with sodium ethoxide (10% CH3CH2ONa 224g) in ethanol solution (40.5) for 3H, and the product was post-treated to obtain 171.1g, M. P. 171.6 ~ 95% ℃, content> 80%, yield. Preparation of methyl 2-formate benzenesulfonyl isocyanate see preparation method of metsulfuron-methyl. Synthesis of aminosulfuron-methyl 2-amino-4-methylamino-6-ethoxy-mesyl-triazobenzene 17.7g was dissolved in 6000mL of dichloromethane, and 27.3g of methyl-o-formate benzenesulfonyl isocyanate was added dropwise to the solution for 3H at room temperature, the solution gradually became milky white, and was allowed to stand, filtered and dried to obtain 35g,m. P. 195 °c, content> 93%, yield> 80%. |
