As significant technical difficulties exist and the presence of the actual named test substance in aqueous solution is doubtful, 

the current OECD Guidelines 107 or 117 are not suitable for determining the octanol-water partition coefficient of this compound.  

Therefore, testing will not be conducted and data generated by property-estimation software (e.g., KOWWIN version 1.67) 

will be reported instead.
