Final Results
The water solubility CS of Dehydrothiotoluidine monosulfonic acid was determined at 20°C in distilled water according to the "flask method" described in the European Commission Council regulation (EC) No 440/2008, Annex, Part A, A.6., OECD-guideline 105 and the US EPA Product Properties Test Guideline OCSPP 830.7840.
The concentrations of the test item were determined by HPLC analysis. The reversed-phase HPLC method used was found to be valid. The results of the solubility measurements are shown in the following Table:
