Chlorosulfonyl Isocyanate (CAS 1189-71-5), often abbreviated as CSI, is a chemical compound characterized by its high reactivity and versatility, making it a cornerstone in various industrial synthesis processes. Understanding its intrinsic chemical properties is essential for chemists, R&D scientists, and product formulators looking to leverage its capabilities effectively and safely.
As a colorless transparent liquid with a molecular formula of CClNO3S and a molecular weight of 141.53, CSI is known for its potent electrophilic nature. This property allows it to readily react with a wide array of nucleophiles, including amines, alcohols, and acids, forming new chemical bonds and enabling the construction of complex organic molecules. This reactivity is fundamental to its use as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and polymers. For professionals looking to buy Chlorosulfonyl Isocyanate, knowing these properties helps in selecting the right grade and handling protocols.
The compound's boiling point is approximately 107°C, and its density is around 1.626 g/mL at 25°C. It is important to note that CSI is moisture-sensitive and reacts violently with water, necessitating careful storage and handling. Typically supplied with an assay of 99.2% or higher, its purity is critical for achieving predictable outcomes in sensitive chemical reactions. When sourcing this reagent, it is crucial to partner with a reliable supplier that guarantees these specifications.
