Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It plays a key role in the development of kinase inhibitors and other targeted therapies due to the presence of the trifluoromethylpyrazole moiety, which enhances metabolic stability and binding affinity. The carboxylic acid and Boc-protected amine groups allow for easy functionalization, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in solid-phase and solution-phase peptide-like synthesis for drug discovery.
