Used as a chiral building block in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure supports the formation of complex molecules with high enantioselectivity. Commonly employed in the preparation of neuroactive compounds and kinase inhibitors due to its ability to mimic peptide motifs and enhance metabolic stability. Also utilized in agrochemicals for the synthesis of bioactive molecules requiring specific stereochemical configuration.
