Chlorosulfonic acid is a highly reactive, colorless to yellowish liquid with a strong, pungent odor. It is primarily used as a sulfonating agent in organic synthesis, particularly for the production of sulfonic acids, detergents, and pharmaceuticals. This acid is also employed in the manufacture of dyes, plasticizers, and in the petroleum industry for refining purposes. Due to its corrosive nature and ability to release toxic fumes, chlorosulfonic acid must be handled with care in controlled environments.
