Description

[3-(3,5-Dichlorophenyl)Phenyl]Sulfonyl Chloride is a high-purity, bifunctional aromatic intermediate of significant importance in advanced organic synthesis. Its core value lies in its dual reactive sites—the sulfonyl chloride group and the halogenated aromatic ring—which enable its use as a versatile building block for constructing complex molecular architectures. This compound is primarily needed by research and development chemists and process engineers in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and insecticides, leveraging its aromatic halogen and sulfonyl chloride functionalities.
• Material Science: Serves as a monomer or cross-linking agent in the production of specialty polymers, such as poly(arylene ether sulfone)s, for high-performance applications.
• Chemical Research: Employed in academic and industrial R&D for exploring novel organic reactions and creating complex, multi-functional molecules.
• Ligand and Catalyst Development: Acts as a starting material for synthesizing specialized ligands used in transition metal catalysis.

Quality Control

Our [3-(3,5-Dichlorophenyl)Phenyl]Sulfonyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing all specifications are provided with each shipment.

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 degradation. Keep away from strong acids, bases, and oxidizing agents.
