Description

6-Bromo-2,2,4,4-tetrafluoro-1,3-benzodioxane is a high-purity fluorinated organic building block, specifically a brominated benzodioxane derivative, with the CAS number 261762-36-1. This compound is valued for its unique molecular architecture, which combines a halogenated aromatic core with a fluorinated dioxane ring, making it a versatile intermediate for advanced synthesis. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing complex molecules, particularly in the development of new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of novel drug candidates, especially those requiring fluorinated or halogenated aromatic scaffolds.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides, where the fluorine and bromine atoms can enhance biological activity and environmental stability.
• Material Science Research: Acts as a precursor for specialty polymers, liquid crystals, or organic electronic materials due to its rigid, halogenated structure.
• Organic Synthesis Building Block: Employed in cross-coupling reactions (e.g., Suzuki, Stille) and nucleophilic substitutions to introduce functionalized benzodioxane units into more complex molecules.
• Chemical Research & Development: A valuable tool for medicinal and process chemists exploring structure-activity relationships (SAR) and developing new synthetic methodologies.
