Description of key information

Based on a weight of evidence assessment the auto flammability temperature for isoamylene (2-methylbutene) is 275ºC.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
548.2 K

Additional information

In the absence of a reliable key study, a weight of evidence assessment was used to determine this endpoint. Two studiesLide(2008) and Lewis (2007) were used. The Lide (2008) study concerns pent-1-ene and is considered a suitable substance for read-across
