Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive agents and renin inhibitors. Its structure supports the creation of compounds that modulate enzyme activity involved in blood pressure regulation. Also employed in research for designing new bioactive molecules due to its fused ring system, which enhances binding affinity to biological targets. Shows potential in the preparation of nootropic and neuroprotective agents. Commonly utilized in medicinal chemistry for scaffold modification to improve pharmacokinetic properties.
