693 K

Additional information

The CRC Handbook (Lide, 2008) is peer-reviewed and is considered reliable and suitable for use as the key study for this endpoint. In addition, this value is consistent with the value cited in the EU RAR (2002) for 1,3-butadiene, and is supported by data from the peer reviwed International Chemical Safety Data Card (WHO ICSC, 2000).
