Sulfamic acid is widely used as a descaling agent in industrial and household applications. It effectively removes rust, limescale, and other mineral deposits from boilers, heat exchangers, and cooling systems. Its ability to dissolve hard water deposits makes it a popular choice for cleaning coffee machines, dishwashers, and other appliances.

In the textile industry, it is utilized as a chlorine stabilizer in bleaching processes, ensuring consistent and safe results. It also acts as a catalyst in esterification and nitration reactions in organic synthesis.

Additionally, sulfamic acid is employed in the pulp and paper industry to break down lignin and improve the quality of paper products. Its strong acidic properties and relatively low corrosiveness make it a versatile and efficient chemical in various industrial processes.
