Description

The 5-Bromobenzene-1,3-dicarbaldehyde (CAS No. 120173-41-3) is a high-purity aromatic aldehyde compound with the molecular formula C₈H₅BrO₂. This versatile chemical building block features two formyl groups positioned meta to each other on a brominated benzene ring, making it an essential intermediate for organic synthesis, pharmaceutical research, and material science applications. Its unique structure enables selective functionalization for the development of complex molecules, ligands, and polymers.

Our product is rigorously tested to ensure ≥95% purity (HPLC/GC) and is supplied as a crystalline solid with excellent stability under recommended storage conditions. It is ideal for use in cross-coupling reactions, Schiff base formation, and as a precursor for heterocyclic compounds. The bromo substituent enhances reactivity in palladium-catalyzed transformations, while the dual aldehyde functionality allows for sequential derivatization.

Available in research quantities (100mg to 10g) with optional certificates of analysis. Suitable for laboratory use only – not for drug, household, or food applications. Store in a cool, dry place protected from light at 2-8°C.
