- Executive summary:
A study was conducted to determine the solubility of the test substance, TMAC C (98.4% active), in organic solvents using the flask method, according to the OECD 105 Guideline, in compliance with GLP . Under the study conditions, the solubility of the substance in isopropanol, n-hexane and n-octanol was determined to be 614, < 2.14 x 10-4 and 243 g/L, respectively, at 20°C. The substance showed no temperature dependence of solubility (Brekelmans, 2012).
