Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the preparation of monoamine oxidase inhibitors (MAOIs) for the treatment of depression and neurological disorders. It serves as a building block in organic synthesis due to its hydrazine functionality, enabling the formation of heterocyclic compounds such as indoles and pyrazolines. Also employed in research settings for modifying bioactive molecules and developing novel psychoactive substances. Its reactivity makes it valuable in the creation of specialized reagents and functionalized derivatives in medicinal chemistry.
