EC number: 601-472-6
CAS number: 117314-20-2
Flask method: water solubility <0.51 µg/L at 20 °C (EU Method A6 and OECD 105 with slight deviations, GLP)
During the preliminary study the water solubility of the sodium
form test item was estimated to be < 0.005 mg/L. Method A6 Water
solubility (440/2008/EC) recommends that the column elution method
should be used if the water solubility is < 1x10^-2 g/L. However, since
the substance is insoluble in organic solvents, the column elution
method could not be applied.
Using the flask method, the sample solution signals in the main
test with the sodium form were below the limit of detection (LOD = 5.10
x 10^-7 g/L). Similarly, the water solubility of the sodium/hydrogen
form was determined to be less than or equal to 7.43 x 10^-6 g/L. The
substance is therefore very poorly soluble in water.
Mass based distribution (100 μm sieve): particle size of less than 100 μm: 1.01 - 2.92 % (EC EUR 20268, GLP)
A screening test consisting of sieving a known amount of test item with
a 100 μm mesh concluded that only 2.92 % of the sodium form test item
passed through the sieve and are inhalable. Only 1.01 % of the
sodium/hydrogen form test item passed through the sieve and are
Gas comparison pycnometer: relative density 2.83 - 2.97 (OECD 109, EU Method A3 with slight deviations, GLP)
Even though the test temperature deviated from the one determined in
Method A3 (440/2008/EC), the effect on the final results can be
neglected in the case of a solid substance. With the exception of the
test temperature, the method was followed and the density of the sodium
form test item was determined to be 2.83 x 10^3 kg/m^3 at 22.4 ± 0.5 °C
and to have a relative density of 2.83. The density of the
sodium/hydrogen form was determined to be 2.97 x 10^3 kg/m^3 at
22.3 ± 0.5 °C and to have a relative density of 2.97.
