Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of dyes and pigments with enhanced thermal stability. Shows potential in medicinal chemistry for designing inhibitors targeting specific enzymes due to its ability to form stable hydrogen bonds. Also employed in the preparation of azo-free colorants for textiles and polymers, offering improved color fastness and reduced environmental impact. Its hydrazine and pyrazole moieties contribute to metal chelation, making it useful in sensors for detecting metal ions in environmental and industrial samples.
