Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of azo dyes which are valued for their color fastness and wide range of hues. It also serves in the manufacture of certain agricultural chemicals, including herbicides and fungicides, due to its ability to act as a building block in more complex molecules. Additionally, it finds use in the development of specialty polymers and pharmaceuticals where chlorinated aniline derivatives enhance stability and bioactivity. Its methoxy and chloro functional groups allow for selective reactions, making it valuable in fine chemical synthesis.
