2.5 PARTITION COEFFICIENT
Partition coefficient : octanol-water
Log pow : 1.4 at 24.5 °C
pH value : 7.9
Method : other (measured): Directive 79/831/EEC
Year : 1987
GLP : yes
Test substance : other TS: o-Toluidine, purity is not specified
Method : Analytical method: GC/FID
Result : 3 experiments were carried out and the results of the log octanol-water
partition coefficient were: 1.39, 1.40 and 1.41.
As result the mean value of these 3 single values was considered.
Reliability : (2) valid with restrictions
Study well documented
Flag : Critical study for SIDS endpoint
09.06.2004 (22)
Partition coefficient : octanol-water
Log pow : 1.32 at 25 °C
pH value :
Method :
Year : 1979
GLP :
Test substance : other TS: o-Toluidine, purity is not specified
Remark : Three values are given in 1979: 1.29, 1.32, and 1.4 from 3 different
sources.
In the 1995 publication: 1.32 is the preferred log Kow. At pH 7.5, a log Kow
of 1.42 is reported.
