Used as a chiral building block in organic synthesis, particularly in the pharmaceutical industry for the preparation of enantiomerically pure compounds. Its strained epoxide ring undergoes regioselective and stereospecific ring-opening reactions with nucleophiles, enabling the synthesis of complex molecules such as beta-blockers, antiviral agents, and other bioactive intermediates. Also employed in the production of specialty polymers and fine chemicals where stereochemistry is critical. Due to its chirality, it is valuable in asymmetric synthesis and catalysis research.
