Used primarily as an intermediate in the synthesis of azo dyes and pigments, this compound plays a key role in the production of colorants for textiles, inks, and coatings. It is also employed in the preparation of certain pharmaceuticals and agrochemicals, where hydrazine derivatives serve as building blocks for heterocyclic compounds. Due to its reactivity, it facilitates the formation of hydrazone structures, which are important in the development of functional materials and bioactive molecules. Its use, however, requires careful handling due to potential toxicity and instability under certain conditions.
