Description

Ethylicin CAS NO 682-91-7 is a specialized organosulfur compound, also known as ethanesulfonyl chloride, widely recognized for its role as a key sulfonylation reagent and synthetic intermediate. Its high reactivity makes it a critical building block for introducing the ethanesulfonyl group into target molecules, enabling the synthesis of pharmaceuticals, agrochemicals, and advanced materials. This product is essential for research and development chemists, process engineers, and manufacturers in the pharmaceutical, fine chemical, and specialty chemical industries who require a reliable and high-purity sulfonating agent.

Application

• Pharmaceutical Intermediate: A crucial reagent for the sulfonylation of amines and alcohols in the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of sulfonamide-based drugs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents where the ethanesulfonyl moiety is a key functional group.
• Polymer & Material Science: Serves as a modifier or cross-linking agent in the synthesis of specialty polymers, resins, and functional materials.
• Fine Chemical Production: Employed in custom synthesis and the manufacture of dyes, pigments, and other complex organic molecules requiring sulfonyl chloride chemistry.
• Research & Development: A valuable tool in academic and industrial R&D labs for exploring new synthetic pathways and creating novel chemical entities.

Quality Control

Our Ethylicin is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by titration and impurity profiling by gas chromatography (GC) or HPLC. A Certificate of Analysis (COA) detailing purity, identity, and specific test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from strong bases and organic solvents. Due to its reactive nature as an acid chloride, it should be stored separately from incompatible materials such as amines, alcohols, and oxidizing agents. Use appropriate corrosion-resistant storage equipment.
