Description

Pentafluorophenyl 3-Bromo-Benzenesulfonate is a specialized organosulfur and organofluorine compound that serves as a high-value synthetic intermediate. Its core value lies in its dual functionality, combining a highly reactive sulfonate ester group with an electron-deficient pentafluorophenyl moiety, making it a powerful reagent for selective derivatization and cross-coupling reactions. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise building blocks for developing active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of complex drug candidates, particularly those requiring sulfonamide or aryl ether linkages.
• Agrochemical Synthesis: Used in the development of novel herbicides and fungicides where the introduction of fluorine and bromine atoms enhances biological activity and environmental stability.
• Polymer Chemistry: Acts as a monomer or cross-linking agent for creating specialty polymers with unique surface properties, thermal stability, or chemical resistance.
• Ligand and Catalyst Development: Employed in the preparation of sophisticated ligands for transition metal catalysis, leveraging the sulfonate group for attachment to various scaffolds.
• Material Science Research: Utilized in surface modification and the creation of self-assembled monolayers (SAMs) for electronic and sensor applications.
• Chemical Biology Probes: Serves as a reagent for labeling biomolecules or modifying peptides and proteins in bioconjugation strategies.

Quality Control

Our Pentafluorophenyl 3-Bromo-Benzenesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your R&D and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can compromise reactivity. Keep away from incompatible materials such as strong bases and reducing agents.
