Method
The substance has been tested for water solubility according to the flask method as reported in the OECD 105 Guideline.
Results
The water solubility of the substance is 32440 mg/l. The substance is very soluble in water.
Reference
Preliminary solubility result
Reference samples and extract were first measured in the range 190 / 800 nm, so as to choose the right wavelength for quantitative measurements.
Since absorbance of the test solution kept the same proportions along the UV and visible spectra, preliminary test result was considered for the final result calculations. Wavelength chosen was 521.50 nm.
Test results
Reference solutions were measured in the spectrophotometer in quantitative mode, thus generating a calibration curve. Calibration curve was smooth and linear at every concentration. Considering that preliminary test resulted in an absorbance keeping the same shape like the references, its value was considered for the 24 hours’ measurement.
