Additional information

One experimental data and one literature data are available to determine the adsorption coefficient of TBEP.

According to the key experimental study, performed in compliance with OECD Guideline 121 and EU Method C19 under GLP, the log Koc of TBEP was determined to be 2.5 (equal to a Koc value of 299.2) using the HPLC Method. Based on this value, TBEP can be classified to be medium mobile.
