3. Pesticides and Dyes: Intermediates in the synthesis of highly effective and low-toxicity pesticides and organic dyes/pigments. Novel pesticides, high-performance dyes and pigments.
4. Academia and Research: 4-Bromobenzaldehyde CAS 1122-91-4 used to construct more complex organic molecules; a commonly used reagent in basic research. Novel functional molecules, ligands, polymer materials, etc.
1. Dual Reactivity: Possessing both a bromine atom (capable of coupling and substitution reactions) and an aldehyde group (capable of oxidation, reduction, and condensation reactions), a single molecule can undergo multiple transformations.
2. Directing Reactivity: The bromine atom on the benzene ring is a meta-directing group, and the aldehyde group is an ortho- or para-directing group. This allows for the introduction of new groups at specific positions on the benzene ring and the directed synthesis of complex molecules.
3. Relative Stability: Stable under normal temperature and dry conditions, facilitating storage and transportation.
