Used as a key intermediate in the synthesis of bioactive molecules and pharmaceuticals, particularly in the development of kinase inhibitors and anticancer agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for constructing peptide-like frameworks and enzyme inhibitors. Also employed in the preparation of fluorescent probes and labeling reagents due to its amine and amide groups, which facilitate conjugation with dyes and biomolecules. Commonly found in research settings for drug discovery and biochemical assays.
