NC-106(QX214NC) Editic acid (Ethyiene diamine tetraacetic acid)
(1)Molecular Weight & Molecular Formula
M=292.2C10H16N2O8
CAS:60-00-4
(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.
