Additional information

The CRC Handbook (Lide, 2008) is a peer-reviewed handbook and is considered reliable and suitable for use as the key study for this endpoint. In addition, this value is used in the EU RAR (2002) for 1,3-butadiene. The Merk Index (2006) also a peer reviewed handbook, gives a melting point of -108.966°C and supports the value reported in the key study.
