Endpoint:
partition coefficient
Type of information:
experimental study
Adequacy of study:
key study
Study period:
October 16, 2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The analytical test was performed utilizing the EU A8 guideline. The laboratory maintains accreditation from AALA in the field of chemical testing and operation of a laboratory quality managemnet syste. This analytical test was conducted outside the scope of the facility's accreditation. However, the data and results contained within this report were generated an obtained utilizing analytical methods, testing and reporting procedures and practices consistent with valid, internationally accepted,well-documenetd and scientifically acceptable guidelines.
Guideline:
EU Method A.8 (Partition Coefficient)

GLP compliance:
not specified
Type of method:
other: individual solubilities
Partition coefficient type:
octanol-water
Type:
log Pow
Partition coefficient:
>= 0
Temp.:
25 °C
pH:
>= 12.2
Remarks on result:
other: pH was measured in the 1% concentration solution only.
Details on results:
HH - N-[3-(dimethylamino)propyl]-N,N',N'-trimethylpropane-1,3-diamine was miscible in all proportions in both n-octanol and water. Given the miscibility, no further testing was conducted in either octanol or water. The solubility value for n-octanol was approximated at > 900,000 mg/L. The solubility value for water was approximated at > 900,000 mg/L.
Conclusions:
The octanol-water partition coefficient of HH - N-[3-(dimethylamino)propyl]-N,N',N'-trimethylpropane-1,3-diamine was determined by a comparison of solubilities, based on the EU A8 guideline. The log Pow was determined to be 0 at 25 degrees C.

Additional information

HH - N-[3-(dimethylamino)propyl]-N,N',N'-trimethylpropane-1,3-diamine was miscible in all proportions in both n-octanol and water. Given the miscibility, no further testing was conducted in either octanol or water. The solubility value for n-octanol was approximated at > 900,000 mg/L. The solubility value for water was approximated at > 900,000 mg/L. Therefore, the log Pow was determined to be 0 at 25 degrees C.
