Used in pharmaceutical synthesis as a protected pyrazole derivative, enabling selective reactions in drug development. The tert-butoxycarbonyl (Boc) group stabilizes the amine during peptide coupling or heterocycle formation, while the oxalate salt enhances crystallinity and handling. Commonly employed in kinase inhibitor and antiviral agent research where the 1H-pyrazol-1-yl moiety acts as a bioisostere. Its structure supports modular assembly of complex molecules in medicinal chemistry, particularly in creating libraries for biological screening.
