Chlorosulfonyl Isocyanate (CSI), CAS 1189-71-5, is a powerful reagent recognized for its high reactivity, making it indispensable in many advanced chemical synthesis processes. NINGBO INNO PHARMCHEM CO.,LTD. provides this compound to industries that require precise chemical transformations, but it is crucial for users to understand its properties for safe and effective utilization. CSI's reactivity stems from the presence of two highly electrophilic centers: the carbon atom of the isocyanate group and the sulfur atom of the chlorosulfonyl group. This dual reactivity allows CSI to undergo a variety of reactions, including [2+2] cycloadditions with alkenes and alkynes, nucleophilic additions, and substitution reactions.

The reactivity profile of CSI means it must be handled with care. It reacts vigorously with water, releasing hazardous fumes. Therefore, reactions involving CSI are typically carried out in dry, inert solvents such as chlorocarbons, ethers, or acetonitrile to prevent unwanted side reactions and ensure process safety. NINGBO INNO PHARMCHEM CO.,LTD. advises all customers to follow strict safety protocols when working with CSI, including using appropriate personal protective equipment (PPE) such as gloves, eye protection, and respiratory protection, especially in well-ventilated areas or under fume hoods. Understanding these handling requirements is key for any chemical company that wishes to buy CSI.

The synthetic utility of CSI is vast, contributing to the creation of beta-lactams, carbamates, and nitriles, among other valuable compounds. Its application in the synthesis of pharmaceuticals, agrochemicals, and advanced materials like battery electrolytes highlights its importance. For companies that need to buy CSI, partnering with NINGBO INNO PHARMCHEM CO.,LTD. ensures access to a product that is not only of high purity but also accompanied by guidance on safe handling and optimal usage. The price of CSI reflects its specialized nature and the critical role it plays in high-value chemical manufacturing.

Proper storage is also essential for maintaining the integrity of CSI. It should be stored in tightly sealed containers in a cool, dry, and well-ventilated area, away from moisture and incompatible materials. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality CSI and supporting our clients with the necessary information to use this powerful reagent effectively and safely in their synthesis operations.
