CAS number: 68953-84-4
Log Kow for the 3 main constituents of 1,4-benzenediamine, N,N'-mixed Ph and tolyl derivatives are: 3.3 ; 3.9 and 4.6.N,N'-diphenyl-p-phenylenediamine; R-59; CAS: 74-31-7: log Kow = 3.3N-(2-methylphenyl)-N'-phenylbenzene-1,4-diamine; R-1679; CAS: 27173-16-6: log Kow = 3.9N,N'-bis(2-methylphenylbenzene)-1,4-diamine; R-898; CAS: 15017-02-4: log Kow = 4.6
Three study reports describing the determination of the n-octanol water
partition coefficient are available.
Two of them are conducted per GLP and OECD guidelines, and the resulting
values for log Kow are in good agreement. As the results are so closely
together, the most recent study is chosen as the key study.
The log Kow value for DAPD, 3.93, was calculated as the average of log
Kow of the 3 main components.
