Additional information

Results of different predicted data for target chemical 3-(bromomethyl)benzonitrile (CAS no. 28188 -41 -2) for partition coefficient endpoint are summarized below.

 

In first predicted data the octanol water partition coefficent (log Pow) of chemical 3-(bromomethyl)benzonitrile (CAS no. 28188 -41 -2) was estimated to be 2.43 at temperature 25oC by using Estimation Program Interface (EPI suite) KOWWIN program V1.68.

 

In another predicted data study the octanol water partition coefficient (log Pow) of chemical 3-(bromomethyl)benzonitrile (CAS no. 28188-41-2) was estimated by using Advanced Chemistry Development /I-lab predictive module and authoritative database Chemspider of Royal Society of Chemistry . Log Pow value estimated to be 2.36 at temperature 25oC.

On the basis of both the studies log Pow value falls in range of 2.36 -2.43 therefore it is concluded that test chemical 3-(bromomethyl)benzonitrile can be considered as hydrophilic in nature.
