Description

3-Bromo-5-(Pentafluorosulfur)Benzyl Bromide is a high-value, multi-functional organofluorine building block. This compound is critical for introducing both bromine and the unique pentafluorosulfur (SF5) functional group into advanced molecular architectures. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical and agrochemical sectors for the synthesis of novel active ingredients and specialty materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting CNS disorders and metabolic diseases.
• Agrochemical Research: Used in creating advanced pesticides and herbicides where the SF5 group enhances biological activity and environmental stability.
• Liquid Crystal & OLED Materials: Serves as a precursor for fluorine-containing components in electronic display technologies and organic semiconductors.
• Polymer Modification: Employed to incorporate bromine and fluorine functionalities into polymer backbones, altering physical and chemical properties.
• Cross-Coupling Reactions: The benzyl bromide moiety is reactive in various palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) for complex molecule assembly.
• Ligand & Catalyst Development: Useful for synthesizing specialized ligands and catalysts used in asymmetric synthesis and industrial catalysis.

Quality Control

Every batch of 3-Bromo-5-(Pentafluorosulfur)Benzyl Bromide is manufactured and analyzed under strict quality management protocols. We provide comprehensive analytical data including HPLC purity, NMR (1H, 19F, 13C) confirmation, and GC-MS analysis to ensure identity and consistency. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting compliance with our stringent internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
