Used as a chiral building block in the synthesis of pharmaceuticals and fine chemicals. Commonly employed in the production of antiviral and antibacterial agents due to its stereochemical purity. Serves as an intermediate in the preparation of prodrugs and active pharmaceutical ingredients (APIs), especially where enantioselectivity is critical. Also utilized in the formulation of some cosmetics and personal care products for its moisturizing and solubilizing properties. Its (S)-configuration allows for specific interactions in biological systems, making it valuable in asymmetric synthesis and drug development.
