Heterocyclic building block
Used as a thiophene-based intermediate in chemical synthesis, particularly within the C7 to C9 building-block range. The combination of a reactive ring and a ketone group makes it a versatile scaffold for constructing more elaborate molecules.
Cross-coupling substrate
The carbon-bromine bond at the 5-position provides a handle for palladium-catalysed cross-coupling reactions such as Suzuki, Stille and Negishi couplings. This allows the thiophene core to be elaborated into biaryl and extended conjugated systems.
Carbonyl chemistry
The propanoyl (ethyl ketone) substituent supports standard carbonyl transformations, including reduction, condensation and reductive amination. It is a convenient point for introducing further functionality onto the thiophene ring.
Research and discovery chemistry
As a halogenated thiophene reagent, it is applied in exploratory and medicinal-chemistry research where substituted thiophenes are required. Tech Serve Solutions supplies it for laboratory-scale investigation and method development.
