Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antihypertensive and antiarrhythmic agents. It serves as a building block in the preparation of amidine-containing heterocycles, which are important in medicinal chemistry for their biological activity. Commonly employed in research settings to construct more complex molecules through coupling reactions or cyclization processes. Its bromoaryl group allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in drug discovery and development.
