Description

4-Bromo-1H-indazole (CAS No. 186407-74-9) is a high-purity brominated heterocyclic compound with the molecular formula C₇H₅BrN₂. This aromatic indazole derivative is a versatile building block in organic synthesis, particularly in pharmaceutical and agrochemical research. The compound features a bromine substituent at the 4-position of the indazole ring, offering a reactive site for further functionalization via cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig).

Our product is rigorously tested to ensure ??98% purity (HPLC/GC), with detailed analytical data (NMR, MS) available upon request. Supplied as a white to off-white crystalline powder, it is packaged under inert conditions to ensure stability. Ideal for medicinal chemistry, it serves as a precursor for kinase inhibitors, anticancer agents, and other bioactive molecules. Store in a cool, dry place at 2-8??C, protected from light and moisture.

Application

4-Bromo-1H-indazole is widely used as a key intermediate in the synthesis of pharmacologically active compounds, including kinase inhibitors and antitumor agents. Its bromine moiety enables efficient palladium-catalyzed cross-coupling reactions for constructing complex heterocycles. Researchers also employ it in fragment-based drug discovery and as a scaffold for PET tracer development. The compound’s indazole core is notable for mimicking purine bases, making it valuable in nucleotide analog studies.
