Description and Uses

Sulfamic acid is widely used in electroplating, hard-water scale reremovers, acidic cleaning agent, chlorine stabilizers, sulfonating agents, denitrification agents, disinfectants, flame retardants, herbicides, artificial sweeteners and catalysts.
Sulfamic acid is a precursor to sweet-tasting compounds. Reaction with cyclohexylamine followed by addition of NaOH gives C6H11NHSO3Na, sodium cyclamate.
Sulfamic acid is a water-soluble, moderately strong acid. An intermediate between sulfuric acid and sulfamide, it can be used as a precursor to sweet-tasting compounds, a therapeutic drug component, an acidic cleaning agent, and a catalyst for esterification.
