Storing and handling Fluazifop-butyl
Reactivity
FLUAZIFOP BUTYL is a trimethyl phenoxy pyridine ester. May react with acids to liberate heat. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. May generate heat with caustic solutions. Genreates flammable hydrogen with alkali metals and hydrides.
