Description of key information
There is data available for this substance. Additionally, key data is available for structural analogues, Heptane and Nonane and presented in the dossier. The data is read across to this substance based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.
According to Lide (2005) the partition coefficient for Normal-Heptane is 4.5.
According to Lide (2005) the partition coefficient for octane is 5.15.
According to Lide (2005) the partition coefficient for nonane is 5.65.
Key value for chemical safety assessment
Additional information
For the purpose of PBT assessment (Annex XIII), a combination of QSAR models and experimental data for both screening and assessment level information are utilized, in accordance with REACh Annex XI and ECHA Guidance on integrated testing and evaluation strategies (R.11). As a result, single values or ranges of values reported for individual endpoints within the substance registration should be considered within this weight of evidence context and not applied individually for the purpose of PBT assessments. A complete, integrated PBT assessment for the range of relevant constituents within petroleum hydrocarbon UVCB substances is attached to this dossier (section 13.2).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
