Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of cardiovascular drugs and PDE3 inhibitors. Its structure supports the modulation of enzyme activity, making it valuable in creating agents that influence heart function and blood circulation. Also explored for use in central nervous system therapies due to its ability to cross the blood-brain barrier. Commonly employed in structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
