The pure product is colorless crystal, and the industrial product is light yellow aqueous solution, which is weakly alkaline, has the smell of nitrogen and hydrogen sulfide, is soluble in water, and has stable chemical properties, but it is easy to decompose when the temperature exceeds 40 degrees.
