Additional information
The study was conducted in accordance with OECD guideline 117 and GLP. The acceptance criteria of the Study Plan were met, deeming the results acceptable. From the data presented, the n-Octanol/Water Partition Coefficient (log Pow) of the Test Article at retention time of 1.38 minutes was determined to be 1.44. (excluding thiourea) and the two injections of Test Article demonstrated Pow values that differed by 0.06 log units. The mean result was 1.44 at retention time of 1.38.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
