Property

CAS No.: 5329-14-6 Formula: H3NO3S Molecular Weight: 97.09370

Description

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.
Sulfamic acid (H3NSO3) may be considered an intermediate compound between sulfuric acid (H2SO4), and sulfamide (H4N2SO2), effectively – though see below – 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.
