SULFURIC ACID
Sulfamic acid, is colourless crystals, aqueous solution is acidic, chemical formula HSO3NH2 . The chemical formula is HSO3NH2. The melting point is 205℃, soluble in liquid nitrogen, ethanol, formamide, acetone, slightly soluble in methanol, insoluble in ether. The aqueous solution of sulfamic acid has the same strong acidity as hydrochloric acid, sulfuric acid, etc., so it is also called solid sulfuric acid, which is non-volatile, odourless and has the characteristics of very low toxicity to human body. The product aqueous solution of iron corrosion products act slowly, can add some sodium chloride, so that the slow generation of hydrochloric acid, so as to effectively dissolve the iron scale sulfamic acid cleaning agent used in a wide range, it is still the only can be used as galvanised metal surface cleaning acid. With water and sulfamic acid when 4:1. It can corrode egg shells and can be used to clean boilers, condensers, heat exchangers, jackets and chemical pipelines.

The most famous application of that is in the synthesis of compounds that taste sweet. Reaction with cyclohexylamine followed by addition of NaOH gives C6H11NHSO3Na, sodium cyclamate. Related compounds are also sweeteners, see acesulfame potassium.
Sulfamates (O-substituted-, N-substituted-, or di-/tri-substituted derivatives of sulfamic acid) have been used in the design of many types of therapeutic agents such as antibiotics, nucleoside/nucleotide human 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 is used as an acidic cleaning agent, typically for metals and ceramics. It is a replacement for hydrochloric acid for the removal of rust. In households, it is often found as a descaling agent in detergents used for removal of limescale.
