Physical and chemical properties:

Property: White needle-like crystals that turn brown or black when stored for a long time. Pure products are white needle-like crystals, soluble in water, ether or alcohol. Slightly soluble in benzene, sublimation by heating, easily oxidized in the air, and then turned brown or black.

Solubility: soluble in water, ethanol and ether; slightly soluble in benzene. It turns red when met with ferric chloride. It reacts with inorganic acids to form salts that are easily soluble in water.
