Used as a key intermediate in organic synthesis, particularly in the preparation of complex pharmaceuticals and bioactive molecules. Its strained epoxide ring allows selective ring-opening reactions, enabling the introduction of functional groups in a stereocontrolled manner. Commonly employed in the synthesis of β-blockers and other cardiovascular drugs due to its ability to form chiral building blocks. Also utilized in agrochemical synthesis for creating structurally diverse compounds with enhanced biological activity. Its tert-butyl ester group facilitates easy purification and protection during multistep syntheses.
