Description

2,6-Dibromobenzenesulfonyl Chloride is a high-purity, multi-functional chemical intermediate essential for advanced organic synthesis. Its core value lies in its dual functionality as both a sulfonylating agent and a halogenated aromatic building block, enabling precise molecular construction. This compound is critically needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and pesticides where the dibromo-substituted benzene ring provides specific bioactivity.
• Material Science: Serves as a precursor for functional polymers, liquid crystals, and advanced organic electronic materials due to its rigid, halogenated structure.
• Chemical Research & Development: A versatile reagent for introducing the 2,6-dibromobenzenesulfonyl moiety into complex molecules in medicinal and process chemistry.
• Dye & Pigment Industry: Intermediate in the synthesis of specialized colorants and photographic chemicals.
• Cross-coupling Reactions: The bromine atoms serve as handles for further functionalization via metal-catalyzed cross-coupling reactions like Suzuki or Buchwald-Hartwig amination.

Quality Control

Our 2,6-Dibromobenzenesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability for your critical R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and 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, oxidizing agents, and moisture.
