H3NO3S
H3NO3S, commonly known as sulfamic acid, is an inorganic compound with the formula H3NSO3. The molecule consists of an amino group bound to a sulfonic acid group, and is often represented as H2N–SO3H. In solid form, sulfamic acid is a white, crystalline, hygroscopic substance that is highly soluble in water. It is stable under ordinary conditions but can decompose when heated, releasing gases containing sulfur and nitrogen.
Sulfamic acid is widely used as a descaling and cleaning agent due to its ability to dissolve
