Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of thiophene-based bioactive molecules. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex organic frameworks. Commonly employed in the preparation of antihypertensive agents, antiviral compounds, and functional materials. Also utilized in the design of organic semiconductors and conjugated polymers due to the electron-rich nature of the thiophene ring.
