Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of compounds with biological activity such as kinase inhibitors and antimicrobial agents. It serves as a building block in medicinal chemistry due to the presence of both amine and amide functional groups, which allow for further derivatization. Commonly employed in the preparation of heterocyclic compounds and in solid-phase peptide synthesis where selective reactivity is required. Also utilized in research settings for labeling and probing biochemical pathways.
