4-Bromo-1H-pyrrolo[2,3-b]pyridine-3-carboxylic acid(Cat No.:L044847)is a heterocyclic aromatic compound with the molecular formula C8H5BrN2O2. It features a fused pyrrole-pyridine ring system substituted with a bromine atom at position 4 and a carboxylic acid at position 3. This structure makes it a valuable intermediate in medicinal chemistry, particularly in the synthesis of kinase inhibitors and other biologically active molecules. The bromine atom enables further functionalization via cross-coupling reactions, such as Suzuki or Heck reactions. It is typically used in research and drug discovery under controlled laboratory conditions with appropriate safety precautions.
