Cas no 947149-96-4 (2-Bromo-4,5-dihydro-thieno[2,3-c]pyran-7-one)
2-Bromo-4,5-dihydro-thieno[2,3-c]pyran-7-one is a heterocyclic compound featuring a fused thienopyranone scaffold with a bromine substituent at the 2-position. This structure imparts reactivity suitable for further functionalization, making it a valuable intermediate in organic synthesis, particularly for pharmaceutical and agrochemical applications. The presence of the bromine atom enhances its utility in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, enabling the construction of complex molecular architectures. Its rigid bicyclic framework also offers potential as a building block for bioactive molecules. The compound is typically handled under inert conditions due to its sensitivity to moisture and air. High purity grades are available for research and industrial use.
