Air & Water Reactions

Insoluble in water.

Reactivity Profile

2,4,5-T, ISOBUTYL ESTER is an ester of a chlorinated organic acid. May react exothermically with acids to generate isobutyl alcohol and 2,4,5-trichlorophenoxyacetic. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat may also be generated with caustic solutions.

Fire Hazard

Flash point data for 2,4,5-T-ISO-BUTYL ESTER are not available. 2,4,5-T-ISO-BUTYL ESTER is probably combustible.
