Product Description:

4-Bromo-2-nitrobenzaldehyde is an aromatic organic compound featuring both a bromo and a nitro substituent on the benzaldehyde core. It is a pale yellow to yellow crystalline powder with a molecular formula of C7H4BrNO3. This compound is primarily utilized as a versatile building block in organic synthesis. The presence of three distinct reactive sites—the aldehyde group, the bromine atom, and the nitro group—makes it a valuable precursor for constructing more complex molecules. It is commonly employed in cross-coupling reactions (e.g., Suzuki, Heck) via the bromine atom, while the aldehyde and nitro groups can undergo further transformations such as condensation, reduction, or cyclization. Its applications are predominantly in research and development for synthesizing pharmaceuticals, agrochemicals, and functional materials. For instance, it serves as a key intermediate in the synthesis of various heterocyclic compounds and biologically active molecules.
