Used primarily as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and bioactive molecules. Its structure allows for functionalization at multiple sites, making it valuable in constructing complex cyclic frameworks. Commonly employed in the preparation of cyclopentane-based analogs for drug discovery, especially in central nervous system agents and anti-inflammatory compounds. Also utilized in the synthesis of specialty esters and amides due to the presence of the carboxylic acid and ketone functionalities. Its rigid cyclopentane core enhances stereoselectivity in reactions, beneficial for asymmetric synthesis.
