Used in organic synthesis for the preparation of various pharmaceutical intermediates. It acts as a key reagent in the acylation process, enabling the introduction of cyclopentanepropionyl groups into target molecules. Commonly employed in the production of active pharmaceutical ingredients (APIs) for drugs targeting neurological and cardiovascular conditions. Also utilized in the development of agrochemicals and specialty chemicals, where its reactivity with amines and alcohols is leveraged to create complex structures. Its role in peptide coupling reactions makes it valuable in biochemical research and drug discovery.
