CAS 3518-65-8: 1-Chloromethanesulfonyl chloride

Description: 1-Chloromethanesulfonyl chloride, with the CAS number 3518-65-8, is an organosulfur compound characterized by the presence of a chloromethyl group and a sulfonyl chloride functional group. It appears as a colorless to pale yellow liquid and is known for its strong reactivity, particularly as a sulfonating agent. This compound is highly polar due to the sulfonyl group, which enhances its solubility in polar solvents. It is sensitive to moisture and can hydrolyze in the presence of water, releasing hydrochloric acid and forming methanesulfonic acid. 1-Chloromethanesulfonyl chloride is primarily used in organic synthesis, particularly for the introduction of sulfonyl groups into various organic molecules, making it valuable in the production of pharmaceuticals and agrochemicals. Due to its reactivity, it must be handled with care, as it can cause severe irritation to the skin, eyes, and respiratory system. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound.
