Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its hydrazine functionality allows for easy derivatization, making it valuable in constructing nitrogen-containing heterocycles. Commonly employed in the preparation of pyrimidine-based drug candidates and in medicinal chemistry research for scaffold diversification. Also utilized in the synthesis of agrochemicals and functional materials due to its reactivity and ability to form stable conjugates with carbonyl compounds.
