Chlorosulfonyl lsocyanate

Chlorosulfonyl isocyanate is a highly reactive, extremely toxic, and corrosive colorless liquid that strongly irritates the respiratory tract and skin. It reacts violently with water and serves as a crucial intermediate in organic synthesis for producing pharmaceuticals, pesticides, dyes, and other compounds. It is commonly employed to introduce sulfonyl or isocyanate functional groups, serving as a cornerstone for synthesizing various functional organic compounds.
