Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes that exhibit bright shades and good lightfastness. It also serves in the production of certain pharmaceuticals, where its nitro and amino functional groups allow for further chemical modifications to build active ingredients. Additionally, it finds use in agrochemical synthesis, contributing to the development of herbicides and pesticides. Its aldehyde group enables condensation reactions useful in creating heterocyclic compounds for research and industrial applications.
