Uses and applications

What the substance is used for, by industry and function

Intermediate in organic synthesis.

How it is made

From diazotized m-chloroaniline

By hydrolysis of 1,3-dichlorobenzene with cupric salts & hydroxylamine, by vapor phase hydrolysis of 1,2,4-trichlorobenzene in the presence of a phosphate catalyst

The mono-, di-, or trihalogenated phenols having at least one chlorine atom in a meta position ... cannot be obtained by the chlorination of phenol, but must be made by other types of reactions, such as hydrolysis, sulfonation, hydrodechlorination, hydroxylation, and alkylation. (Mono-, Di-, and Trichlorophenols with Chlorine in a Meta Position)
