Used as an intermediate in organic synthesis, particularly in the preparation of cyclopentane-based compounds for pharmaceuticals and agrochemicals. Its ester and carboxylate functionalities allow for further chemical modifications, such as hydrolysis, decarboxylation, or coupling reactions. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where a substituted cyclopentyl ring is required. Also utilized in the development of specialty polymers and fine chemicals due to its structural rigidity and reactivity.
