Uses and applications

What the substance is used for, by industry and function

Selective pre-planting herbicide (former use).

How it is made

Benzotrifluorides are also important in the production of pesticides. The key intermediate, 4-chloro-3,5-dinitrobenzotrifluoride, is obtained by dinitration of 4-chlorobenzotrifluoride. Reaction with secondary amines gives ... profluralin.

It can be made by reacting 4-chloro-3,5-dinitro benzotrifluoride with n-cyclopropylmethyl-n-n-propylamine.
