Sulfamic acid, also known as amidosulfonic acid, amidosulfuric acid, aminosulfonic acid, and sulfamidic acid, is a molecular compound with the formula H3NSO3. This colorless, water-soluble compound finds many applications. Sulfamic acid melts at 205 °C before decomposing at higher temperatures to H2O, SO3, SO2, and N2.[2]

Sulfamic acid (H3NSO3) may be considered an intermediate compound between sulfuric acid (H2SO4), and sulfamide (H4N2SO2), effectively replacing an –OH group with an –NH2 group at each step. This pattern can extend no further in either direction without breaking down the –SO2 group. Sulfamates are derivatives of sulfamic acid.

    I have been using surgical spirit for years but recently it's very hard to get hold of. Luckily Amazon sell this so ordered some just to keep back. It can be used for a number of things so handy to have a bottle in. It's only a small bottle but you don't need much.
