Product name: Fenvalerate HazardClass: 6.1b PackingGroup: Ⅲ Chemical name: (S)-α-cyano-3-phenoxybenzyl(S)-2-(4-chlorophenyl)-3-methylbutyrate CAS NO.: 51630-58-1 Molecular Formula: C25H22ClNO3 Molecular weight: 419.9 Specification: TC:purity≥92%, Formulation:20%EC physicochemical property: Brown sticky liquid, density 1.26 (26 ℃), boiling point more than 200 ℃ (1.0 mmHg), melting point 59.0~ 60.2 ℃, vapor pressure 2.6 x 10-7 MMHG (20 ℃). Almost insoluble in water, soluble in xylene, acetone, chloroform etc.organic solvent. Burning point: 420 ℃, flash point more than 200 ℃. Storage stability more than two years in room temperature. Technical for yellow to brown sticky liquid, a portion of the crystal precipitation at room temperature, distill decomposition. Stable in hot, humid and acid acid medium, hydrolytzed in alkaline medium rapidly. Poisonousness: Fenvalerate is medium toxicity pesticides, rat LD50 451 mg/kg through mouth, rat LC50 > 101 mg/m3 by breathing, slight irritation for rabbit skin, middle irritation for human eyes. No mutagenic and carcinogenic, teratogenic effect. High toxicity for the bees, poultry, fish, shrimp, etc. When using, don't pollute rivers, ponds, mulberry field and apiary. Application: Fenvalerate insecticidal spectrum wide, natural enemies to no selective to tag and stomach toxicity effect is given priority to, no inner suction and fumigation action. To lepidoptera larva effect is good. To homoptera, orthoptera, hemiptera insect pests such as also have better effect, but to mite is invalid. Suitable for cotton, fruit, vegetables, soy, wheat and other crops. Packing: TC: 200l/Iron drum or as customerized
