Sulfamic acid Structure and reactivity
The compound is well described by the formula H3NSO3, not the tautomerH2NSO2(OH). The relevant bond distances are S=O, 1.44 and S–N 1.77 Å.
The greater length of the S–N distance is consistent with a single bond. Furthermore, a neutron diffraction study located the hydrogen atoms, all three of
which are 1.03 Å distant from nitrogen. In the solid state, the molecule of sulfamic acid is well described by a zwitterionic form:
is mainly a precursor to sweet-tasting compounds. Reaction with cyclohexylamine followed by addition of NaOHgives C6H11NHSO3Na, sodium cyclamate.
Related compounds are also sweeteners, see acesulfame potassium. Sulfamates have been used in the design of many types of therapeutic agents such as antibiotics,
nucleoside/nucleotidehuman immunodeficiency virus (HIV) reverse transcriptase inhibitors, HIV protease inhibitors (PIs), anti-cancer drugs (steroid sulfatase and
carbonic anhydrase inhibitors), anti-epileptic drugs, and weight loss drugs.
Sulfamic acid Cleaning agent
is used as an acidic cleaning agent, sometimes pure or as a component of proprietary mixtures, typically formetals and ceramics.
It is frequently used for removing rust and limescale, replacing the more volatile and irritatinghydrochloric acid, which is however cheaper.
It is often a component of household descaling agents, for example, Lime-A-Way Thick Gel contains up to 8% sulfamic acid and pH 2–2.2, or detergents used for removal
of limescale. When compared to most of the common strong mineral acids, sulfamic acid has desirable water descaling properties, low volatility, low toxicity.
It forms water-soluble salts of calcium and ferric iron. Importantly, sulfamic acid is preferable to use in household in comparison to hydrochloric acid for its intrinsic safety.
If erroneously mixed with hypochlorite based products such as bleach, it does not form chlorine gas, where the most common acids would; the reaction (neutralization)
with NH3, produces a salt as depicted in the section above. It also finds applications in the industrial cleaning of dairy and brew-house equipment.
Although it is considered less corrosive than hydrochloric acid, corrosion inhibitors are often added to commercial cleansers of which it is a component.
Some of its domestic use, e.g. Easy-Off, for descaling include home coffee and espresso equipment and in denture cleaners.

Advantages of using Sulphamic Acid
Sulphamic Acid has very high shelf life
Sulphamic acid has very high effectivity of the descaling.
The solid can be directly charged to system eliminating the cost of system reduces the leave of scaling solids and acts as anti ? descalant.
Complete cleaning can be chemically achieved by Sulphamic acid and does not require post descaling manual cleaning.
No system required for dosing.
It is recommended to does into the cooling water for descaling the condenser on running plant.
Sulphamic acid is safe acid and has no handling hazards.
Disadvantages of using Sulphamic Acid Provides a strong irritant effect to the skin and mucous membranes of the eyes
