Description of key information

Adsorption/desorption:

The Soil Adsorption Coefficient i.e Koc value of test substance N-ethyl-1-(4-methoxyphenyl)propan-2-amine(CAS no. 14367 -46 -5) was estimated using Adsorption Coefficient module (v12.1.0.50374) program as Koc 1.0 dimensionless (log Koc= 0.0) at pH range 1-7 and at pH range 8-14 Koc value was estimated to be in range 1.78 - 476 (log Koc= 0.2504 -2.6776). By considering log Koc value of pH 7 which is log Koc =0 indicates that the test substance N-ethyl-1-(4-methoxyphenyl)propan-2-amine has a negligible sorption to soil and therefore has rapid migration potential to groundwater.

Additional information

Adsorption/desorption:

Various predicted data studies for target chemical N-ethyl-1-(4-methoxyphenyl)propan-2-amine (CAS No. 14367-46-5) and experimental study for its structurally similar read across chemical have been reviewed for adsorption endpoint and their results are summarized below.

In first predicted data study the Soil Adsorption Coefficient i.e Koc value of test substance N-ethyl-1-(4-methoxyphenyl)propan-2-amine(CAS no. 14367 -46 -5) was estimated using Adsorption Coefficient module (v12.1.0.50374) program of Advanced Chemistry Development /I-lab predictive module as Koc 1.0 dimensionless (log Koc= 0.0) at pH range 1-7 and at pH range 8-14 Koc value was estimated to be in range 1.78 - 476 (log Koc= 0.2504 -2.6776). By considering log Koc value of pH 7 which is log Koc =0 indicates that the test substanceN-ethyl-1-(4-methoxyphenyl)propan-2-aminehas a negligible sorption to soil and therefore has rapid migration potential to groundwater.

Next study was done by using Sci Finder database the soil adsorption co-efficient i.e., Koc value of test chemical N-ethyl-1-(4-methoxyphenyl)propan-2-amine(CAS no. 14367-46-5) at pH range 1-7 was estimated to be 1.0 dimensionless (log Koc = 0.0) and at pH 8, 9 and 10 Koc value was estimated to be 2.31, 18.2 and 141 dimensionless (Log koc = 0.3636,1.2600, 2.1492) respectively at temperature 25 deg.c. these log Koc values suggest that this test chemical has negligible to slow sorption to soil and sediments and therefore has rapid to moderate migration potential to ground water.

Another prediction was done by Using Chemspider-ACD/Phy chem suite the soil adsorption co-efficient i.e., Koc value of test substance N-ethyl-1-(4-methoxyphenyl)propan-2-amine (CAS no. 14367 -46 -5) was estimated to be 1.0 dimensionless (log Koc= 0) at pH 5.5 and pH 7.4 and temperature 25 deg.C This Koc value at different pH indicates that the chemical N-ethyl-1-(4-methoxyphenyl)propan-2-amine has  negligible sorption to soil and sediments and therefore has rapid migration potential to ground water.

Last study was experimental study done by SSS, 2018 in this study the adsorption coefficient Koc in soil and in sewage sludge of test chemical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 121 for testing of Chemicals. The reference substances were chosen according to structural similarity with the test substance and calibration graph prepared. The reference substances were xylene, ethylbenzene and toluene having Koc value ranging from 2.369 to 2.649. The Log Koc value was found to be 1.15385 ± 0.0029 at 25°C. The results indicate that the test chemical has negligible sorption to soil and sediment and therefore has rapid migration potential to ground water.

By considering results of all the studies mentioned above it can be concluded that log Koc value of test chemical N-ethyl-1-(4-methoxyphenyl)propan-2-amine (CAS No. 14367-46-5)is 0.0 dimensionless. This log koc value indicates that test chemical has negligible sorption to soil and sediment and therefore has rapid migration potential to ground water.
