Features

3,5-Difluorobenzoic Acid CAS NO. 455-40-3 is an intermediate for the synthesis of ecdysone insecticides hydrazide and methoxen hydrazide. It can also improve the hardening speed of polyurethane, shorten the demoulding time, synthesize prostaglandins, and synthesize flame retardants. This substance may be harmful to the environment, special attention should be paid to water bodies, and contact with oxides should be avoided.

Production Method

Add 1,3,5-trimethylbenzene and catalyst nickel salt into the oxidation axe, heat it, and pass it into the air to oxidize it.
