Used as a chemical intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes which are widely applied in the textile, printing, and leather industries. It also serves in the manufacture of fluorescent whitening agents and optical brighteners for paper and plastics. Additionally, it has been employed in analytical chemistry as a reagent for the detection of oxidizing agents and in the development of colorimetric sensors. Due to its aromatic amine structure, it can participate in electrophilic substitution reactions, making it valuable in organic synthesis for building more complex molecules.
