Description of key information
Adsorption / desorption
Adsorption study was conducted for estimating the adsorption coefficient (Koc) value of test chemical Anisoyl chloride(CAS no. 100-07-2) (HSDB and PubChem, 2017). The adsorption coefficient (Koc) value was calculated using a structure estimation method based on molecular connectivity indices. The adsorption coefficient (Koc) value of test substance Anisoyl chloride was estimated to be 37 (Log Koc = 1.568). This Koc value indicates that the substance Anisoyl chloride has a low sorption to soil and sediment and therefore have moderate migration potential to ground water.
Additional information
Adsorption / desorption
Experimental study and various predicted data for the target compound Anisoyl chloride (CAS No. 100-07-2) and supporting study for its structurally similar read across substance were reviewed for the adsorption end point which are summarized as below:
In an experimental key study from authoritative database (HSDB and PubChem, 2017), adsorption experiment was conducted for estimating the adsorption coefficient (Koc) value of test chemical Anisoyl chloride(CAS no. 100-07-2). The adsorption coefficient (Koc) value was calculated using a structure estimation method based on molecular connectivity indices. The adsorption coefficient (Koc) value of test substance Anisoyl chloride was estimated to be 37 (Log Koc = 1.568). This Koc value indicates that the substance Anisoyl chloride has a low sorption to soil and sediment and therefore have moderate migration potential to ground water.
In aprediction done using theKOCWIN Program(v2.00) of Estimation Programs Interface (EPI Suite, 2018) was used to predict the soil adsorption coefficient i.e Koc value of test chemical Anisoyl chloride (CAS No. 100 -07 -2). The soil adsorption coefficient i.e Koc value of Anisoyl chloride was estimated to be 11.11 L/kg (log Koc=1.0458) by means of MCI method (at 25 deg C). This Koc value indicates that the substance Anisoyl chloride has a negligible sorption to soil and sediment and therefore have rapid migration potential to ground water.
From CompTox Chemistry Dashboard using OPERA (OPEn (quantitative) structure-activity Relationship Application) V1.02 model in which calculation based on PaDEL descriptors (calculate molecular descriptors and fingerprints of chemical), the adsorption coefficient i.e KOC for test substance Anisoyl chloride was estimated to be 110 L/kg (log Koc = 2.041).The predicted KOC result based on the 5 OECD principles. This Koc value indicates that the substance Anisoyl chloride has a low sorption to soil and sediment and therefore have moderate migration potential to ground water.
In a supporting study from authoritative database (HSDB, 2017) for the read across chemical 1,4-Dimethoxybenzene (CAS no. 150-78-7), adsorption experiment was conducted for estimating the adsorption coefficient (Koc) value of read across chemical 1,4-Dimethoxybenzene (CAS no. 150-78-7). The adsorption coefficient (Koc) value was calculated using an experimental logKow and regression derived equation. The adsorption coefficient (Koc) value of substance 1,4-Dimethoxybenzene was estimated to be 300 (Log Koc = 2.477). This Koc value indicates that the substance 1,4-Dimethoxybenzene has a low sorption to soil and sediment and therefore have moderate migration potential to ground water.
On the basis of above overall results for target chemical Anisoyl chloride (from authoritative database HSDB, PubChem, EPI suite and Comptox Chemistry Dashboard,2017) and for its read across substance (from authoritative database HSDB, 2017), it can be concluded that the Koc value of test substance Anisoyl chloride ranges from 11.11–110 indicating that the test chemical Anisoyl chloride has a negligible to low sorption to soil and sediment and therefore have rapid to moderate migration potential to ground water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
