Description

2-Bromo-6-Fluorobenzenesulphonyl Chloride is a high-purity, reactive organosulfur compound primarily used as a versatile building block in advanced chemical synthesis. Its value lies in its dual functionality as both an electrophilic sulfonylating agent and a halogenated aromatic scaffold, enabling the construction of complex molecules. This intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active ingredients and novel chemical entities.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of sulfonamide-based drug candidates, including enzyme inhibitors and receptor modulators.
• Agrochemical Synthesis: Used in the production of novel herbicides, fungicides, and pesticides that require a halogenated benzenesulfonyl moiety.
• Material Science Research: Serves as a precursor for creating specialized polymers, liquid crystals, and organic electronic materials.
• Chemical Biology & Proteomics: Employed in the design of activity-based probes (ABPs) and affinity labels to study enzyme function.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis projects requiring regioselectively functionalized benzenesulfonyl derivatives.

Quality Control

Our 2-Bromo-6-Fluorobenzenesulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment ensures material consistency and reliability for your critical R&D and production processes.

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 decomposition. Keep away from strong bases and oxidizing agents.
