Description

4,5-Dichloro-Benzene-1,3-Disulfonyldichloride is a high-purity, reactive sulfonyl chloride derivative used as a critical building block in advanced organic synthesis. Its value lies in its dual sulfonyl chloride functionality, which enables the efficient introduction of sulfonamide or sulfonate groups into complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of sulfonamide-based drugs, including diuretics, carbonic anhydrase inhibitors, and antiviral agents.
• Agrochemical Synthesis: Used to create novel herbicides, fungicides, and pesticides by incorporating the sulfonyl moiety into active molecules.
• Polymer Chemistry: Serves as a cross-linking agent or monomer for producing specialty polymers with enhanced thermal or chemical resistance.
• Dye and Pigment Manufacturing: Intermediate for synthesizing sulfonated dyes and organic pigments.
• Material Science Research: Building block for creating metal-organic frameworks (MOFs) or other functional materials requiring precise sulfonation.
• Custom Chemical Synthesis: Employed in contract research and manufacturing (CRAM) for producing tailored sulfonyl-containing compounds for various R&D projects.

Quality Control

Our 4,5-Dichloro-Benzene-1,3-Disulfonyldichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every 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, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, amines, alcohols, and moisture.
