- REASON FOR QSAR ASSESSMENT
A log Koc value is available for the test substance, Bromoform, from a handbook of chemical data; however, the reference lacked any methodological detail and consequently there was some doubt about its reliability. This QSAR assessment was undertaken to strengthen the adsorption / desorption dataset.
QSAR DETAILS
1. MODEL (incl. version number) KOCWIN Module (Version 2.00) of United States Environmental Protection Agencies EPI Suite QSAR Program (version 4.11)
2. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
C(Br)(Br)Br
3. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
The United States Environmental Protection Agencies EPI Suite QSAR Program is a well recognised system for calculation of various environmentally relevant endpoints nad has been used widely for many years. - Reason / purpose for cross-reference:
- other: Reference to handbook data as a comparison with QSAR calculated data. This was to ensure handbook and QSAR calculated data was similar and hence strengthen the confidence in the QSAR.
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- A Quantitative Structure Activity Relationship (QSAR) calculation method was used. The software used was the
KOCWIN (Version 2.00) a module within the United States Environmental Protection Agencies EPI Suite QSAR Program (version 4.11)

- Conclusions:
- The Koc of Bromoform calculated from the Log Kow by KOCWIN (Version 2.00) a module within the United States Environmental Protection Agencies EPI Suite QSAR Program (version 4.11) was 120.9 L/kg. The LogKow was estimated to be 2.08 and the experimental Log Koc matched to an internal database was 2.06.
- Executive summary:
Introduction
A log Koc value is available for the test substance, Bromoform, from a handbook of chemical data; however, the reference lacked any methodological detail and consequently there was some doubt about its reliability. To strengthen the adsorption / desorption dataset a QSAR assessment of the log Koc of Bromoform was therefore also undertaken using the United States Environmental Protection Agencies EPI Suite QSAR Program.
Method
The Log Koc value for Bromoform was calculated using KOCWIN module of United States Environmental Protection Agencies EPI Suite Program (version 4.11). The koc value was derived from the Log pow value.
Result
The Log Koc value calculated by KOCWIN was 2.08. An experimental log Koc of 2.06 was also identified in an internal database of experimental values.
Conclusion
The Koc of Bromoform calculated from the Log Kow by KOCWIN (Version 2.00) a module within the United States Environmental Protection Agencies EPI Suite QSAR Program (version 4.11) was 120.9 L/kg. The LogKow was estimated to be 2.08 and the experimental Log Koc matched to an internal database was 2.06.
