Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification, making it valuable in medicinal chemistry for constructing drug candidates targeting cancer, inflammation, and central nervous system disorders. The carboxylic acid and protected amine functional groups enable stepwise coupling and deprotection strategies in solid-phase or solution-phase peptide-like synthesis. Commonly employed in research settings for building complex heterocyclic systems with improved pharmacokinetic properties.
