Method and Material

Prelim Test: A preliminary test was performed in order to determine the amount of test substance to use in the final test. A sample size of 0.11g of test item was diluted to 1000 mL with purified water. After shaking at 30°C for 69 hours and standing at 20°C for 6 hours, the contents of the flask were passed through a 0.2 um nylon filter and was then analyzed. The pH of the solution was also measured. Definitive Test: Three mixtures/samples were prepared using purified water in three separate flasks. After preparation, each flask was shaken at around 30°C for 24, 48, and 72 hours. Then the flasks were allowed to stand at 20°C for 24 hours. The contents of each flask were filtered through 0.2 um nylon filter and the pH of each solution was measured. HPLC was used to determine the concentration of the test substance in each of the sample solutions.


After the equilibration period, all samples were clear, colorless solutions with excess, undissolved test item present. Upon filtration, all samples were visibly clear, colorless solutions that did not contain any undissolved test item. The water solubility of the test item was determined to be less than or equal to 0.085 mg/L.


The test material is considered to be insoluble in water.
