Insoluble in water.

Reactivity Profile

Butyl 2,4-dichlorophenoxyacetate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Fire Hazard

Flash point data for Butyl 2,4-dichlorophenoxyacetate are not available. Butyl 2,4-dichlorophenoxyacetate is probably combustible.
