Description

Ethyl Fluorosulphonate is a highly reactive organosulfur compound, also known as ethyl fluorosulfonate. This chemical is a powerful alkylating and sulfonating agent, valued for its role in introducing the ethylsulfonyl fluoride group into target molecules. It is primarily utilized in advanced organic synthesis and pharmaceutical research for the production of specialized intermediates. Industries requiring high-purity fluorinated building blocks, such as agrochemicals, pharmaceuticals, and materials science, are the key consumers of this product.

Application

• Pharmaceutical Intermediate Synthesis: A key reagent for constructing complex molecules, particularly in the development of sulfonamide-based drugs and other bioactive compounds.
• Agrochemical Production: Used in the synthesis of novel pesticides and herbicides, where the ethylsulfonyl moiety can enhance biological activity.
• Polymer & Materials Science: Acts as a monomer or modifying agent in the creation of specialty polymers with unique surface properties or chemical resistance.
• Organic Synthesis Reagent: Employed as a potent ethylating agent or for the preparation of other fluorosulfonates in research and development laboratories.
• Chemical Derivatization: Useful in analytical chemistry for derivatizing compounds to improve their detection or chromatographic properties.

Quality Control

Our Ethyl Fluorosulphonate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We support compliance with global regulatory frameworks such as REACH.

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). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
