Used as a chiral building block in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its strained epoxide ring undergoes regioselective and stereoselective ring-opening reactions with various nucleophiles, enabling the formation of complex molecules with defined stereochemistry. Commonly employed in asymmetric synthesis to introduce chirality, it is valuable in the development of active pharmaceutical ingredients (APIs) and natural product analogs. Also utilized in research settings for studying stereospecific reaction mechanisms and enzyme-catalyzed transformations.
