2-Chloroethanesulfonic acid CAS:15484-44-3

2-Chloroethanesulfonic acid, also known as chloroethanesulfonic acid or CES, is an organic compound with the chemical formula C2H5ClSO3H. It is a clear, colorless liquid that is highly soluble in water and polar organic solvents.

CES is widely used as a versatile chemical intermediate in various industries. It is primarily employed in the synthesis of pharmaceuticals, agrochemicals, and organic dyes. Its sulfonic acid group makes it a useful reagent for introducing sulfonic acid functionality into organic molecules, which can enhance their solubility, stability, or bioactivity.

Due to its strong acidity, CES can also be utilized as a catalyst or acidic reagent in organic reactions. Its acidic nature allows it to promote reactions such as esterifications, acylations, and sulfonations. Additionally, it can serve as a pH adjuster, buffering agent, or corrosion inhibitor in industrial processes.
