Sulfamic acid is a white orthorhombic flaky crystal, odorless, non-volatile and non-hygroscopic. Soluble in water and liquid ammonia, slightly soluble in methanol, insoluble in ethanol and ether, also insoluble in carbon disulfide and liquid sulfur dioxide. Its aqueous solution has the same strong acid properties as hydrochloric acid and sulfuric acid, but its corrosiveness to metals is much lower than that of hydrochloric acid. The toxicity is extremely small, but it should not be in contact with the skin for a long time, and it should not enter the eyes.
