(1)   Molecular Weight & Molecular Formula

M=292.2            C₁₀H₁₆N₂O₈

(2)    Properties

The white powder is produced by the crystals in water. The melting point is 240 ⁰C(decomposition). In 25⁰C, its solubility in water is 0.5g/L, and is insoluble in ordinary organic solution. Free acid is not so stable as salt. When heated to 150⁰C, it tends to break away from hydroxyl. It is stable when stored in liquid solution or boiling.
