Description

2,6-Dichloro-4-(Pentafluorosulfur)Benzenesulfonylchloride is a high-value, multi-functional organosulfur building block characterized by its reactive sulfonyl chloride and pentafluorosulfur groups. This compound is critical for the synthesis of advanced sulfonamide derivatives and functional materials, offering unique electronic and steric properties. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel active ingredients and performance materials.

Application

• Pharmaceutical Intermediate: Key precursor for the synthesis of novel sulfonamide-based drug candidates, including enzyme inhibitors and receptor antagonists.
• Agrochemical Active Ingredient Synthesis: Used in the development of next-generation herbicides, fungicides, and insecticides with enhanced efficacy and environmental profiles.
• Material Science: Building block for creating specialty polymers, liquid crystals, and advanced organic electronic materials due to its fluorine content and robust aromatic core.
• Chemical Research & Development: A versatile reagent for introducing the pentafluorosulfanyl (SF5) group, a "super-trifluoromethyl" group, into organic molecules to modulate lipophilicity, metabolic stability, and bioavailability.
• Dye and Pigment Chemistry: Intermediate in the production of high-performance, light-fast dyes and functional pigments.

Quality Control

Every batch of 2,6-Dichloro-4-(Pentafluorosulfur)Benzenesulfonylchloride is manufactured and analyzed under strict quality management protocols. We provide comprehensive analytical data including HPLC purity, NMR (1H, 19F, 13C), and mass spectrometry to ensure identity, strength, quality, and purity. Certificates of Analysis (COA) are available for each lot and can be tailored to meet specific customer or regulatory requirements.

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 decomposition.
