Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for heterocyclic compounds due to its reactive pyrazolidinone core. Commonly employed in the development of active ingredients in crop protection products and medicinal agents, especially those targeting inflammation and pain. Also utilized in research settings for synthesizing derivatives with potential biological activity, including antimicrobial and anti-inflammatory properties. Its hydrochloride form enhances solubility and stability in various reaction conditions, making it suitable for use in aqueous and polar solvent systems.
