Shikimic acid ethyl ester is widely utilized in the synthesis of pharmaceuticals, particularly as an intermediate in the production of antiviral drugs like oseltamivir (Tamiflu). It serves as a key building block in organic synthesis, enabling the creation of complex molecules with therapeutic potential. In research, it acts as a precursor for studying biosynthetic pathways and developing novel compounds with biological activity. Its role in industrial applications includes use as a chiral intermediate in asymmetric synthesis, contributing to the production of enantiomerically pure substances.
