Cas no 1086389-94-7 (2,5-Dibromo-1H-pyrrolo2,3-bpyridine)

2,5-Dibromo-1H-pyrrolo[2,3-b]pyridine is a brominated heterocyclic compound featuring a pyrrolopyridine core structure. This intermediate is valued for its versatility in organic synthesis, particularly in pharmaceutical and agrochemical research, where it serves as a key building block for further functionalization. The presence of two bromine atoms at the 2- and 5-positions enhances its reactivity in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, enabling the introduction of diverse substituents. Its rigid fused-ring system contributes to stability while maintaining compatibility with a range of reaction conditions. The compound is typically handled under inert conditions due to its sensitivity to moisture and air.
