Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other nitrogen-containing heterocyclic compounds. It serves as a building block in agrochemicals for developing herbicides and pesticides due to its reactive functional groups. Also employed in the preparation of dyes and pigments, where the nitro and amino groups contribute to color development and stability. Its chloro and nitro substituents allow for further substitution reactions, making it valuable in organic synthesis and research for creating more complex molecules.
