Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where pyrazole derivatives exhibit biological activity. It serves in peptide coupling and heterocyclic modifications due to the presence of the carboxylic acid group and protected nitrogen. Commonly employed in medicinal chemistry for constructing drug-like molecules, especially in agrochemicals and anti-inflammatory agents. Its Boc-protected structure allows for selective deprotection and further functionalization in multi-step organic syntheses.
