Additional information

Following studies have been conducted to determine log Pow of test chemical.

In first study the experimental value of octanol water partition co-efficient (log Pow) of test chemical is -0.698 at 30 degC and pH of 6.44.

In another study the experimental value of octanol water partition co-efficient (log Pow) of test chemical is -0.958 at 30 degC and pH of 4.50.

These log Pow values indicate that the substance is hydrophilic in nature.
