Description of key information

The dynamic viscosity of 2-methyl-2-butene is 0.203 mPa.s at 25ºC. This value can be used as read-across for isoamylene (2-methylbutene, CAS 26760-64-5).

Key value for chemical safety assessment

Additional information

No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook, Lide (2008) and so can be considered reliable and suitable for use as the key study for this endpoint. The dynamic viscosity of 2-methyl-2-butene is 0.203 mPa.s at 25ºC. Since isoamylene (2-methylbutene,26760-64-5) is a mixture of the two isomers, 2-methylbut-2-ene (513-35-9) and 2-methylbut-1-ene (563-46-2) and in the absence of any reliable data for isoamylene then 2-methylbut-2-ene is considered a suitable substance for read-across.

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.
