Used as a key intermediate in organic synthesis, particularly in the preparation of cyclopropane-containing compounds which are important in pharmaceuticals and agrochemicals. Its aldehyde and ester functional groups allow for diverse transformations, such as condensation reactions, reductions, and cyclizations, enabling the construction of complex ring systems. Commonly employed in the development of biologically active molecules, including antiviral and anti-inflammatory agents, due to the metabolic stability imparted by the cyclopropane ring. Also utilized in the synthesis of natural products where strained ring systems are present.
