Used as an intermediate in the synthesis of shikimic acid pathway compounds, particularly in the production of antiviral agents like oseltamivir (Tamiflu). It serves as a chiral building block in organic synthesis, enabling the development of complex natural products and pharmaceuticals. Its structural features make it valuable for stereoselective transformations in medicinal chemistry. Also employed in biochemical research to study enzyme inhibition and metabolic pathways related to aromatic amino acid biosynthesis.
