Description of key information

Additional information

The substance is a solid with a relative density of 1.44 at room temperature (mp ca. 160 degrees C) which decomposes at 183 degrees C. It has an extrapolated vapour pressure at 20 degrees C of 3e-7 Pa. Note that this vapour pressure is based on measurements at 181.2 degrees C; the measured vapour pressure therefore most likely resulted from volatile decomposition products. The true vapour pressure of the substance may therefore be significantly lower.

Substance is highly water soluble (14 g/L), and its octanol water partition coefficient (-0.83) indicates that it is very hydrophilic. An aqueous solution of 1 g/L has a surface tension of 73 mN/m; as such the substance can be classified as not surface active.

The substance is not flammable (is not susceptible to a thermally initiated reaction with oxygen), and does not self-ignite, up to its melting point. It is not explosive, when tested according to method A.14. It is positive in UN transport of hazardous materials test, series 1, but not in series 2 and 3 tests, so it does not qualify as explosive material according to these criteria either. It is not oxidizing according to test A.17.
