Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective kinase inhibitors and central nervous system agents. Its hydrazine functionality allows for coupling reactions with carbonyl compounds, enabling the formation of hydrazones that serve as building blocks in drug design. Commonly employed in medicinal chemistry for constructing heterocyclic scaffolds such as pyrazoles and triazoles. Also utilized in the preparation of serotonin receptor modulators and antidepressant candidates due to the presence of the methoxybenzyl moiety, which can enhance blood-brain barrier penetration. Shows utility in research settings for labeling and conjugation strategies in biochemical assays.
