Description

3-Chloro-5-(Pentafluorosulfur)Benzenesulfonyl Chloride is a highly functionalized and reactive organosulfur compound, serving as a critical building block in advanced chemical synthesis. Its unique structure, featuring both a sulfonyl chloride and a pentafluorosulfur group, makes it an exceptionally versatile electrophile for introducing complex aromatic sulfonamide and sulfonate functionalities. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical sectors who require sophisticated intermediates for developing novel active ingredients, such as kinase inhibitors and herbicides.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for targeted therapies and kinase inhibitors.
• Agrochemical Synthesis: Used to construct novel sulfonamide-based herbicides, fungicides, and plant growth regulators with enhanced efficacy.
• Material Science: Building block for creating specialty polymers, liquid crystals, and advanced materials with specific surface or electronic properties.
• Chemical Research & Development: A valuable reagent in medicinal chemistry for structure-activity relationship (SAR) studies and library synthesis.
• Dye and Pigment Industry: Intermediate in the production of high-performance, sulfonated dyes and pigments.

Quality Control

Our 3-Chloro-5-(Pentafluorosulfur)Benzenesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistent performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical quality attributes. Our commitment to quality ensures the material meets the stringent requirements for research and cGMP-grade pharmaceutical intermediate applications.

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. Keep away from moisture, strong bases, and oxidizing agents.
