Used as a reactive intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its epoxide and ester functional groups allow for selective ring-opening reactions and carbon-chain elongation. Commonly employed in the synthesis of beta-blockers and other bioactive molecules where chiral centers are required. Also utilized in polymer chemistry to modify resin properties, enhancing flexibility and adhesion. Due to its ability to undergo catalytic reduction and nucleophilic attack, it serves as a building block in multi-step synthetic routes.
