Description of key information

The registered substance was found to undergo hydrolysis at pH 7 and 9 only, with estimated half-lives (at 25°C) of 994 hours and 18.1 hours respectively (EU Method C.7). Based on the key biodegradation study (OECD Guideline 301D), the registered substance is considered to be readily biodegradable. The bioconcentration factor (BCF) of the C6 and C7 isomers of the substance were estimated with a QSAR model (BCFBAF model v3.01 from EPI Suite v4.1, using experimental log Kow value at 4.46) at 215 L/kg whole body weight and 222 L/kg whole body weight, respectively. Finally, the adsorption coefficient (log Koc) of the substance was determined to be 4.0 (OECD Guideline 121 and EU Method C.19). This result indicates that the registered substance is immobile in soil (according to P.J. McCall et al., 1980).
