Description

Ethanesulfonyl Isocyanate is a highly reactive organosulfur compound characterized by its isocyanate functional group attached to an ethanesulfonyl moiety. This unique structure makes it a valuable versatile building block for the synthesis of sulfonylurea derivatives and other specialized chemicals. It is primarily utilized by pharmaceutical intermediates manufacturers and agrochemical research facilities for developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of sulfonylurea-based drug candidates and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Building block for creating novel herbicides and pesticides with sulfonylurea activity.
• Polymer Chemistry: Used in the production of specialty polymers and coatings, where the isocyanate group enables cross-linking.
• Chemical Research & Development: Serves as a versatile electrophile in organic synthesis for introducing the ethanesulfonyl group.
• Ligand and Catalyst Preparation: Precursor for synthesizing specialized ligands and catalysts used in asymmetric synthesis.
• Material Science: Employed in the surface modification of materials to alter their chemical properties.

Quality Control

Our Ethanesulfonyl Isocyanate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality management system is designed to meet the rigorous standards required for research and industrial synthesis applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize degradation and maintain stability. Due to its highly volatile and reactive nature, keep away from heat, sparks, open flames, strong acids, and organic solvents. Use appropriate inert gas (e.g., nitrogen) for headspace purging of opened containers to prevent moisture ingress and polymerization.
