Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: KOWWIN v.1.68 (U.S. Environmental Protection Agency)
Principles of method if other than guideline:
The calculation of the octanol water partition coefficient (log Kow) was performed using KOWWIN v.1.68 (U.S. Environmental Protection Agency) on a personal computer running Windows 7. The struc-ture was entered into KOWWIN by SMILES notations. KOWWIN uses a "fragment constant" method-ology to predict log KOW. For a complete description of KOWWIN's methodology see W.M. Meylan and P.H. Howard, "Atom/Fragment Contribution Method for Estimating Octanol-Water Partition Coeffi-cients", Journal of Pharmaceutical Sciences, Vol. 84, No. 1, January 1995, p. 83 - 91.
GLP compliance:
no
