This compound and carbon monoxide react with aromatic rings in a variant of the Friedel-Crafts reaction named for Gatterman and Koch. This compound and sodium sulfate are generated by the Mannheim process, and the production of soda ash, before the Solvay process was developed, generated this compound as a major by-product in the Leblanc process. This compound, essential for pickling steel, is used with zinc-mercury amalgam in the Clemmensen reduction. The major component of stomach acid, it is paired with nitric acid in aqua regia. For 10 poin
