Used as a chiral building block in the synthesis of pharmaceuticals and biologically active compounds. Its fluorinated alkyl chain enhances metabolic stability and lipophilicity, making it valuable in drug design, particularly for CNS-targeted agents. The presence of two hydroxyl groups allows for further functionalization, such as esterification or ether formation, enabling incorporation into larger molecular structures. Commonly employed in asymmetric synthesis due to the stereochemical purity of the (S)-enantiomer, it contributes to the development of enantioselective drugs and fine chemicals.
