Used as a key intermediate in organic synthesis, particularly in pharmaceuticals and agrochemicals. Its strained cyclopropane ring enhances reactivity, making it valuable in cycloaddition and ring-opening reactions. Commonly employed in the preparation of cyclopropane-containing bioactive molecules, including certain antiviral and anti-inflammatory agents. Also utilized in the synthesis of specialty polymers and flavor/fragrance compounds due to its ester functionality and structural rigidity.
