1,3-Dibromo-4,6-difluorobenzene丨CAS 28342-75-8

1,3-Dibromo-4,6-difluorobenzene (CAS 28342-75-8) is an important halogenated aromatic compound primarily used as a chemical intermediate in organic synthesis. Its main application is in the production of pharmaceuticals, agrochemicals, and specialty chemicals, where it serves as a building block for constructing more complex molecules. The presence of bromine and fluorine atoms on the benzene ring provides sites for selective functionalization through cross-coupling reactions, nucleophilic substitutions, and other halogenation-based transformations. This makes it particularly useful in synthesizing biologically active compounds, fluorinated drugs, and high-performance materials such as polymers and advanced materials for electronics or specialty coatings. Its stability and reactivity under controlled conditions allow it to be employed both in laboratory-scale synthesis and industrial production.

The benefits of 1,3-Dibromo-4,6-difluorobenzene arise from its versatility and efficiency as a synthetic intermediate. Its dual halogen substitution provides chemists with multiple reactive sites, enabling precise structural modifications and facilitating the design of target molecules with desired chemical or biological properties. In pharmaceutical synthesis, it allows for the creation of fluorinated derivatives that often exhibit improved metabolic stability, bioavailability, and activity. In material science, derivatives of this compound contribute to polymers and specialty chemicals with enhanced thermal, chemical, or electronic properties. Its use reduces the number of synthetic steps needed to achieve complex structures, improving yield, cost-effectiveness, and process efficiency.
