Used as an intermediate in the synthesis of pharmaceuticals and dyes, particularly in the development of analgesic and anti-inflammatory drugs. It also serves as a key component in the production of azo dyes and photographic developers due to its reactivity and ability to form stable complexes. Its structure supports coupling reactions in dye manufacturing, enhancing color fastness and intensity. Additionally, it finds use in research settings for developing new heterocyclic compounds with potential biological activity.
