Description

2-Bromo-3-Fluorobenzenesulphonyl Chloride is a high-purity, multi-functional chemical building block essential for advanced organic synthesis. Its value lies in its dual reactive sites—the sulphonyl chloride and halogenated aromatic ring—which enable precise molecular construction. This compound is primarily needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries for creating novel active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used to construct novel herbicides, fungicides, and insecticides by introducing the sulphonyl moiety into active molecules.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers and advanced functional materials.
• Chemical Biology & Proteomics: Employed as a reactive handle for labeling proteins or modifying biomolecules in probe development.
• Dye & Pigment Manufacturing: Acts as an intermediate for synthesizing complex sulfonated colorants and optical brighteners.
• Custom Synthesis & Contract Manufacturing: A critical starting material for bespoke chemical synthesis services targeting niche applications.

Quality Control

Every batch of 2-Bromo-3-Fluorobenzenesulphonyl Chloride is manufactured under strict quality management systems and undergoes rigorous analytical testing to ensure consistency and purity. Our products are supported by comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant ISO and cGMP guidelines where applicable, ensuring reliability for critical research and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 heat, sparks, and open flames.
