Used in the synthesis of pharmaceutical intermediates, particularly in the development of serotonin receptor modulators. It serves as a key building block in medicinal chemistry for creating compounds with potential antipsychotic or antidepressant activity. Also employed in the preparation of organic semiconductors due to its electron-rich heterocyclic structure, making it valuable in materials science for optoelectronic devices. Its bromine functionality allows for further cross-coupling reactions, enabling the construction of complex molecules in research and development settings.
