Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive aldehyde and bromine functional groups. The compound serves in cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex thiophene-based structures. Commonly applied in the development of conductive polymers and organic semiconductors for electronic devices. Also utilized in the preparation of dyes, sensors, and biologically active molecules, including antifungal and anti-inflammatory agents. Its versatility in heterocyclic chemistry makes it valuable in medicinal and materials research.
