Benzyl (2S)-2-hydroxypropanoate is primarily employed as a chiral synthon in asymmetric pharmaceutical synthesis, particularly for prostaglandins and β-lactam antibiotics. It serves as a flavor precursor in food-grade applications due to its mild fruity-lactonic notes. Researchers utilize it to develop biodegradable polymers with controlled stereochemistry. The compound also functions as a protecting group reagent in peptide chemistry and carbohydrate chemistry.
