Chlorosulfuric acid, ethyl ester

Description:
Chlorosulfuric acid, ethyl ester, also known as ethyl chlorosulfate, is an organosulfur compound characterized by its chlorosulfate functional group. It is a colorless to pale yellow liquid with a pungent odor, and it is highly reactive and corrosive. The compound is soluble in organic solvents but reacts vigorously with water, releasing hydrogen chloride gas and forming sulfuric acid. Ethyl chlorosulfate is primarily used as a reagent in organic synthesis, particularly in the preparation of sulfates and sulfonates, and as an alkylating agent in various chemical reactions. Due to its corrosive nature, it requires careful handling and storage in appropriate materials to prevent degradation. Safety precautions are essential when working with this substance, as it can cause severe burns and respiratory irritation. Its applications extend to the production of surfactants, pharmaceuticals, and agrochemicals, making it a valuable compound in industrial chemistry.
