Used in pharmaceutical research as a chiral building block for synthesizing antiviral drugs, including treatments for influenza such as oseltamivir (Tamiflu). Serves as an intermediate in the production of shikimic acid pathway-related compounds. Employed in biochemical studies to investigate metabolic pathways in plants and microorganisms. Also utilized in the development of sensors and analytical methods due to its distinct stereochemistry. Found in natural sources like coffee and some fruits, it contributes to the study of dietary polyphenol metabolism and antioxidant activity.
