Reference
In the HPLC chromatograms of MORTRACE SB CONC, using detection at 210 nm, one large and six smaller peaks were observed. It was assumed that the large peak derived from the major component of test substance whereas the smaller peaks derived from impurities. The corresponding Pow values were calculated 25x105 (log Pow = 6.4) for the major component and 0.63x105 (log Pow = 4.8), 1x105 (log Pow = 5.0), 6.3x105 (log Pow = 5.8), 10x105 (log Pow = 6.0), > 10x105 (log Pow > 6.2) and 20x105 (log Pow = 6.3) for the impurities.
Description of key information
Using the HPLC method, log Pow has been measured for this substance. See value below.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 6.4
- at the temperature of:
- 23 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
