Used as a key intermediate in organic synthesis, particularly in the preparation of cyclopropane-containing pharmaceuticals and agrochemicals. Its bromine and ester functionalities allow for further transformations, such as cross-coupling reactions or nucleophilic substitutions, enabling the construction of complex cyclic structures. Commonly employed in medicinal chemistry for modifying molecular rigidity and improving metabolic stability in drug candidates. Also utilized in the synthesis of bioactive molecules where the cyclopropane ring acts as a conformational constraint.
