Used primarily as an intermediate in organic synthesis, this compound plays a key role in the preparation of pharmaceuticals and bioactive molecules. Its hydrazine core and substituted aromatic groups make it valuable in constructing nitrogen-containing heterocycles, such as pyrazolines and indoles, which are common scaffolds in drug development. It is also employed in the synthesis of selective receptor ligands and enzyme inhibitors, particularly in research targeting central nervous system disorders and inflammatory conditions. Due to the hydrochloride salt form, it exhibits improved stability and solubility, facilitating its use in aqueous or polar reaction media.
