Details on results:
Determination of the partition coefficient of Tetrahydro-Pyridine-Tosilate was based on the measurement of retention time of the test and reference items by reverse phase HPLC method. The retention times of the test and reference items were determined in two replicates injecting twice both of them. The test item was dissolved in methanol and diluted in the mobile phase (methanol/ultrapure water (60:40)) to obtain a final concentration of 100 mg/l.

Conclusions:
The value of partition coefficient of Tetrahydro-Pyridine-Tosilate (CAS No. 201855-54-1) was determined by Microsoft Office Excel 2013: logPow= <0.5
