Used in pharmaceutical synthesis as a key intermediate for nitrogen-containing heterocyclic compounds, particularly in the development of kinase inhibitors and anti-inflammatory agents. Its structure supports cyclization reactions that form bioactive pyrazole derivatives. Also employed in agrochemical research for designing novel pesticides with improved selectivity. The hemisulfate salt form enhances solubility and stability during reaction processes, making it suitable for aqueous-phase synthesis. Additionally, explored in materials science for constructing functionalized polymers with thermal stability.
