Product Overview

3,5-Dibromobenzaldehyde (CAS 56990-02-4) is a dibrominated benzaldehyde derivative with the molecular formula C₇H₄Br₂O and a molecular weight of 263.91 g/mol. The compound features a benzaldehyde core with bromine atoms at the 3- and 5-positions. This compound is a valuable building block for the synthesis of pharmaceuticals, agrochemicals, and functional materials via cross-coupling reactions.

Synthetic Process

The synthesis typically involves the bromination of benzaldehyde under controlled conditions using bromine or N-bromosuccinimide (NBS), or the oxidation of the corresponding dibromotoluene.

Mechanism of Action

The aldehyde group enables nucleophilic addition, condensation, and oxidation reactions. The bromine atoms provide handles for cross-coupling reactions (Suzuki, Sonogashira, etc.).
