Description of key information

Adsorption/desorption:

The Adsorption Coefficient of test substance Reaction mass of Ethanaminium, N-[4-[[4-(diethylamino)phenyl]phenylmethylene]-2,5-cyclohexadien-1-ylidene]-N-ethyl- & acetate was determined as per the HPLC method (OECD Guideline-121). The Log Koc value was determined to be  2.115 dimensionless at 25°C. Thus based on the result it is concluded that the test substance  Reaction mass of Ethanaminium, N-[4-[[4-(diethylamino)phenyl]phenylmethylene]-2,5-cyclohexadien-1-ylidene]-N-ethyl- & acetate  has a low sorption to soil and sediment and therefore has moderate migration potential to ground water.

Additional information

Adsorption/desorption:

The adsorption coefficient Koc in soil and in sewage sludge of test chemical Reaction mass of Ethanaminium, N-​[4-​[[4-​(diethylamino)​phenyl]​phenylmethylene]​-​2,​5-​cyclohexadien-​1-​ylidene]​-​N-​ethyl-​ & acetate was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 121 . The reference substances were chosen according to functional similarity with the test substance and calibration graph prepared.

The reference substances were 4-methylaniline(p-Tolouidine), N-methylaniline, Aniline, Xylene, Ethylbenzene, Toluene, Naphthalene, were chosen having Koc value range from 1.9 to 2.75. The Log Koc value was determined to be 2.115 dimensionless at 25°C.

 

Thus based on the result it is concluded that the test substance Reaction mass of Ethanaminium, N-​[4-​[[4-​(diethylamino)​phenyl]​phenylmethylene]​-​2,​5-​cyclohexadien-​1-​ylidene]​-​N-​ethyl-​ & acetatehas a low sorption to soil and sediment and therefore has moderate migration potential to ground water.
