Physicochemical properties: white or off white crystalline powder, easily soluble in hot water; Slightly soluble in cold water and sensitive to light. After drying at 110 ℃, it melts at about 200 ℃ and decomposes slightly. 1g is dissolved in 150ml water, dissolved in sodium hydroxide solution and slightly soluble in ethanol. It is not precipitated by iodine test solution and potassium iodide test solution, but can be precipitated when it meets trinitrophenol. At pH 2, the maximum absorption wavelength is 260.5nm（ ε 13200), minimum absorption wavelength 229nm, absorbance ratio A250 / a260 = 0.76, A280 / a260 = 0.38

Purpose: biochemical research. Drug analysis.
