Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective monoamine oxidase inhibitors (MAOIs) for neurological research. Its hydrazine functionality allows for facile derivatization, making it valuable in creating analogs for structure-activity relationship (SAR) studies. It is also employed in the preparation of bioactive molecules targeting central nervous system disorders, including depression and Parkinson’s disease. Additionally, it serves as a building block in the formation of heterocyclic compounds used in medicinal chemistry and drug discovery pipelines.
