Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of phosphodiesterase 4 (PDE4) inhibitors. These inhibitors are targeted for the treatment of inflammatory diseases such as chronic obstructive pulmonary disease (COPD) and asthma. The compound's structure allows for effective binding and modulation of PDE4 enzyme activity, contributing to reduced inflammation. Its acrylic acid moiety and specific ether and ester functionalities make it suitable for further chemical modifications in drug design, enhancing potency and selectivity in active pharmaceutical ingredients.
