Caso 1: Síntesis farmacéutica
In a pharmaceutical research project, scientists aimed to synthesize a new anti - cancer drug. They used 1-bromo-3,5-difluorobenzene as an intermediate. First, they reacted it with a specific amine compound in the presence of a suitable catalyst. The reaction was carried out at a moderate temperature of around 80°C for several hours under an inert gas atmosphere. After purification through column chromatography, they obtained an intermediate product with the desired structure. This intermediate was then further reacted with other reagents to form the final anti - cancer drug. The use of 1-bromo-3,5-difluorobenzene provided a key step in introducing the necessary fluorine and bromine - containing groups into the drug molecule, which was crucial for its biological activity.
Caso 2: Síntesis de polímeros
In a materials science laboratory, researchers were working on developing a new type of high - performance polymer for use in electronic devices. They used 1-bromo-3,5-difluorobenzene as a monomer in a polymerization reaction. The polymerization was carried out in a solution of an organic solvent at a relatively low temperature. The bromine atoms on the 1-bromo-3,5-difluorobenzene molecule were able to react with other monomers to form a polymer chain. The resulting polymer had excellent chemical resistance and thermal stability, which made it suitable for use in protecting electronic components from harsh environments.
