Used primarily in organic synthesis, it serves as a key intermediate in the production of various pharmaceuticals and agrochemicals. Its structure is valuable in the development of compounds with potential biological activity, particularly in the creation of indole-based drugs. It is also employed in research settings to study chemical reactions involving nitro and chloro substituents on indole rings, aiding in the discovery of new therapeutic agents. Additionally, it finds application in the synthesis of dyes and pigments due to its aromatic properties.
