Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of azo dyes where its reactivity allows for efficient coupling processes. It also serves in the manufacture of pharmaceuticals, acting as a building block in the development of active ingredients requiring nitroaromatic and acyl chloride functionalities. Its presence is notable in agrochemical synthesis, contributing to the creation of certain herbicides and insecticides due to its ability to modify molecular structures for enhanced biological activity. Additionally, it finds use in research laboratories for the preparation of specialty chemicals and functionalized aromatic compounds.
