The pH of 0.1mol/L aqueous solution is 5.1. 1g can be dissolved in 18mL cold water, 4mL boiling water, 18mL cold ethanol, 6mL boiling ethanol and 4mL glycerol. The solubility in water can be increased with the addition of hydrochloric acid, citric acid and tartaric acid. The relative density is 1.4347. Melting point 184 ° C (decomposition). Boiling point 300 ℃. The median lethal dose (rat, oral) is 5.14g/kg. irritating. Toxic, serious oral administration can lead to death.
