Description

4-(4-Bromo-Phenoxy)-Benzenesulfonyl Chloride is a specialized aromatic sulfonyl chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its dual reactive sites—the sulfonyl chloride group and the brominated aromatic ring—which enable precise molecular construction for complex target molecules. This high-purity intermediate is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries seeking to develop new active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in creating advanced herbicides and fungicides, leveraging the phenoxy and sulfonyl groups for bioactivity.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for producing high-performance, specialty polymers with specific thermal or chemical resistance.
• Ligand and Catalyst Development: Employed in the preparation of sophisticated ligands for catalytic systems and metal-organic frameworks (MOFs).
• Dyestuff and Pigment Manufacturing: Acts as an intermediate for synthesizing complex organic dyes and pigments with enhanced properties.
• Chemical Research & Development: A versatile reagent for method development and exploring new reaction pathways in academic and industrial R&D labs.

Quality Control

Our production of 4-(4-Bromo-Phenoxy)-Benzenesulfonyl Chloride adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the exacting standards required for synthetic applications. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and consistency for our global customers.

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 (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 heat, open flames, and incompatible materials such as strong bases, amines, and alcohols.
