English description（英文原文，共 1309 字符）
Product Name:Carfentrazone-ethyl
English Name:Carfentrazone-ethyl
CAS No.:128621-72-7
Aliases:Carfentrazone, Ethyl carfentrazone, Fulon
Molecular Formula:C15H14Cl2F3N3O3
Physical Properties:The technical product is a light yellow to yellowish-brown viscous liquid. The pure compound appears as a white to light yellow waxy solid below its melting point. Melting point is about 22.5°C, boiling point about 350°C (with decomposition), relative molecular mass 412.19. It has low vapor pressure, is slightly soluble in water, and readily soluble in acetone, toluene, dichloromethane and other organic solvents. It is relatively stable in acidic media and hydrolyzes under alkaline conditions.
Uses:Carfentrazone-ethyl is a selective triazolinone herbicide. It inhibits protoporphyrinogen oxidase, causing cell membrane disruption and death of broadleaf weeds. It is used in wheat, barley, rice, corn and other crop fields to control broadleaf weeds such as Descurainia sophia, Capsella bursa-pastoris, Galium aparine and Euphorbia helioscopia, with low use rates and rapid action.
Technical Specifications:
Active ingredient content ≥95% (technical grade).
Appearance: light yellow to yellowish-brown viscous liquid, free of visible mechanical impurities.
Water content ≤0.5%.
Acidity (as H2SO4) ≤0.3%.
