Description

Benzenemethanesulfonyl Chloride, 2,6-Dibromo- is a specialized aromatic sulfonyl chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its dual functionality, where the sulfonyl chloride group acts as a versatile electrophile for sulfonamide formation, and the bromine substituents provide sites for further cross-coupling reactions. This compound is essential for researchers and process chemists in the pharmaceutical and agrochemical industries, particularly for developing novel active ingredients and complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of sulfonamide-based drug candidates, including protease inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used to construct novel sulfonylurea or sulfonamide herbicides and fungicides with enhanced activity.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers and functional materials.
• Chemical Biology & Proteomics: Employed as an activity-based probe or labeling reagent for studying enzyme mechanisms and protein interactions.
• Custom Synthesis & Contract Manufacturing: A valuable starting material for custom synthesis houses producing high-value, low-volume specialty chemicals.

Quality Control

Every batch of Benzenemethanesulfonyl Chloride, 2,6-Dibromo- is produced and tested under strict quality management protocols. We ensure high purity and consistency suitable for research and scale-up applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
