Used primarily as an intermediate in organic synthesis, especially in the preparation of azo dyes and pigments. It serves as a building block in the development of functional materials, including photochromic and thermochromic compounds. Also employed in the synthesis of pharmaceuticals where hydrazine derivatives are required for constructing heterocyclic systems. Its tert-butyl group enhances solubility and stability in certain reaction pathways, making it valuable in controlled coupling reactions. Additionally, it finds use in research settings for developing novel hydrazine-based ligands and catalysts.
