Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its strained cyclopropane ring and two functionalized carboxyl groups make it valuable for building complex molecular structures. Commonly employed in ring-opening reactions, cyclization processes, and as a precursor for bioactive molecules such as antiviral or anti-inflammatory agents. Also utilized in the synthesis of specialty polymers and ester derivatives for fragrance and flavor applications.
