EC number: 293-927-7
CAS number: 91648-65-6
Key information: Partition coefficient (OECD 117, HPLC method): Pow > 2.5 x 10E9, logPow > 9.4 at 30 °C.Supporting information: Partition coefficient (OECD 107, shake flask method): logPow range: 1.72 - 2.94 at 21 °C.
The key value was determined by High
Performance Liquid Chromatography (HPLC) according to OECD 117 / EU
Method A.8 (Fox, 2012). Further information is available from an
experiment conducted according to OECD 107, revealing a logPow range of
1.72 - 2.94 at 21 °C (Rocchio, 1990). In this case, the test material
stock solution prepared in methanol rather than octanol as recommended.
For purpose of exposure assessment
calculations, a logKow of 8.0 was taken into consideration, since this
value represents the maximum valid logKow value in the algorithms of
EUSES or EU-TGD approach.
