EC number: 627-083-1
CAS number: 244235-47-0
Values of two main peaks:
log Pow 1= 4.8 at 25°C
log Pow 2= ≥ 5.7 at 25°C
The determination was carried out by HPLC method. The
test item elutes with two main peaks.
Triphenylamine exhibits the second highest log Pow value
listed in the EU test procedure (5.7). DDT exhibits the highest log Pow
value (6.2), but was not used due to toxicological reasons.
The first peak (4.8) is assumed to be not reacted
starting material (Nonylphenol) and the second peak (>=5.7) is assumed
to be the reaction product. Identification of the peaks was missed,
because the result of the characterization was not available when phys-chem
tests were commissioned.
