Description

2-(4-Methoxyphenyl)Benzenesulphonyl Chloride, also known as 4-[2-(Chlorosulphonyl)Phenyl]Anisole, is a high-value sulfonyl chloride derivative that serves as a critical building block in advanced organic synthesis. This compound is essential for introducing the benzenesulfonyl moiety, a key functional group in the development of active pharmaceutical ingredients (APIs) and specialty agrochemicals. It is primarily sought by research and development chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries for creating novel sulfonamides and other complex molecules.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of sulfonamide-based drugs, including enzyme inhibitors and receptor antagonists.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and insecticides that require a sulfonyl chloride functional group.
• Fine Chemical Production: Employed as a versatile reagent for introducing sulfonyl groups into complex organic molecules in custom synthesis.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of specialty polymers and advanced materials.
• Dye and Pigment Manufacturing: Utilized in the synthesis of sulfonated dyes and colorants for improved solubility and properties.

Quality Control

Our 2-(4-Methoxyphenyl)Benzenesulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency for your critical processes.

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