It is generally a white, odorless rhomboid flake crystal with a relative density of 2.126 and a melting point of 205°C. Water and liquid ammonia, as long as they are kept dry and not in contact with water at room temperature, the solid sulfamic acid does not absorb moisture and is relatively stable.
