AI Product Description

*The following content is generated by AI and is for reference only.

4-Bromobenzo[b]thiophene is a specialized heterocyclic organic compound widely utilized in medicinal chemistry and materials science as a versatile synthetic intermediate. Its molecular formula is C8H5BrS, reflecting the integration of a bromine atom onto the benzo[b]thiophene core structure. The Compound carries the CAS Registry Number 3167-28-0, which serves as its unique identifier for chemical databases and regulatory compliance. This molecule features a fused bicyclic system comprising a benzene ring fused to a thiophene ring, with a bromine substituent positioned at the fourth carbon of the thiophene moiety. The primary utility of 4-Bromobenzo[b]thiophene lies in its role as a key building block for cross-coupling reactions, particularly Suzuki-Miyaura, Stille, and Negishi couplings. The presence of the aryl bromide bond provides a highly reactive site for palladium-catalyzed transformations, allowing chemists to efficiently attach diverse functional groups such as alkynes, boronic acids, or stannanes. Consequently, it is extensively employed in the synthesis of advanced pharmaceutical agents, including potential anti-inflammatory drugs, kinase inhibitors, and other bioactive molecules targeting specific disease pathways. Beyond pharmacology, this compound is increasingly valuable in the development of organic electronic materials. Researchers utilize it to construct conjugated polymers and small molecules for organic light-emitting diodes (OLEDs) and organic photovoltaic cells (OPVs), where the sulfur-containing heterocycle enhances charge transport properties and stability. Handling this substance requires standard laboratory safety precautions, as it may be an irritant and should be stored under inert atmospheres to prevent degradation. Its availability from various chemical suppliers makes it accessible for both academic research and industrial scale-up processes. As the demand for novel therapeutic compounds and high-performance organic semiconductors grows, 4-Bromobenzo[b]thiophene remains an indispensable reagent in modern chemical synthesis, bridging the gap between fundamental organic chemistry and applied technology. Its structural versatility ensures continued relevance in creating complex architectures for next-generation applications across multiple scientific disciplines.
