INTRODUCTION

3,4-dimethoxyaniline is an aromatic chemical. Its amino function is activated by presence of methoxy groups at meta and para positions and thus the compound readily undergoes many reactions that lead to formation of intermediates used largely in APIs, dyes, and pigments.

Manufacture
It is commercially produced by catalytic reaction between aniline and formaldehyde. Other processes are reduction of 3,4-dimethoxy-nitrobenzene or ammonolysis of 4-chloro-1,2-dimethoxybenzene.
