Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes which are widely applied in the textile industry. It also serves in the preparation of pharmaceuticals, where its functional groups allow for further chemical modifications to build active ingredients. Additionally, it finds use in the development of agrochemicals, including certain herbicides and insecticides, due to its reactivity and structural properties. Its aldehyde, amino, and nitro groups make it valuable in organic synthesis for constructing more complex molecules through condensation, reduction, and other reactions.
