Description

(3,5-Dichloro-Phenyl)-Methanesulfonyl Chloride is a high-purity, reactive sulfonyl chloride derivative, a key building block in advanced organic synthesis. Its value lies in its dual functionality, enabling the introduction of both a sulfonyl group and a reactive chlorine handle for further derivatization. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the production of modern herbicides and fungicides, where the sulfonyl moiety contributes to biological activity.
• Material Science: Serves as a monomer or cross-linking agent in the development of specialty polymers and functional materials.
• Chemical Research: A versatile reagent for constructing complex molecular architectures in medicinal chemistry and process development labs.
• Dye and Pigment Manufacturing: Employed in the synthesis of specialized colorants and photoactive compounds.

Quality Control

Our (3,5-Dichloro-Phenyl)-Methanesulfonyl Chloride is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is 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, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, amines, and alcohols.
