Additional information

The analytical method for the detennination (solubility in water and in octanol) is in agreement with the method that was agreed upon at the "Analytical Experts Meeting" of ETAD (Basel) on January 12,2005.

Because of high extinction coefficient ɛ in sulfuric acid (about 130 l/g*cm at 860 nm) and the very low solubility, an exact value for solubilities in water and in octanol will be not available.

In order to give an indication for a possible logPow value of the test item the estimation method based on the individual solubilities in octanol and in water was applied.
