STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL - Storage condition of test material: at room temperature, protected from moisture - Stability under test conditions: stable - Solubility and stability of the test substance in the solvent/vehicle: Formulations of the test item in parafn oil were found to be homogenous at both concentrations tested (12.5 mg/mL and 250 mg/ mL). Formulations at 12.5 mg/mL and 250 mg/mL were also found to be stable under all conditions i nvestigated (6 hours at room temperature, 10 days at room temperature, at 2-8 °C and at -15 to -35 °C). - Reactivity of the test substance with the solvent/vehicle of the cell culture medium: not applicable TREATMENT OF TEST MATERIAL PRIOR TO TESTING - Treatment of test material prior to testing: The test item was weighed into a tared plastic vial on a suitable precision balance and the vehicle was added to give the appropriate nal concentration of the test item and further vortexing it for 2-3 minutes. To protect from hydrolysis by humidity, the test item and formulation containers were purged with argon after the preparation before closing. - Preliminary purication step (if any): none - Final dilution of a dissolved solid, stock liquid or gel: not applicable- Final preparation of a solid: not app
