Used primarily as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for nitrogen-containing heterocyclic compounds due to its reactive amine functionalities. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous or polar reaction environments. Commonly employed in the development of anti-inflammatory agents and herbicides, where the pyrazolidine core contributes to biological activity. Also utilized in research settings for the synthesis of novel compounds with potential medicinal properties.
