Additional information

The weight of evidence from authoritative secondary sources indicates that the melting point of 1,4 -Butenediol is 10.0 °C at 101.325 kPa (GESTIS, 2010; Grafje et al. 2002). Additonal values from reliable, authoritative secondary sources range from 7 to 8.82°C at 101.325 kPa. These values are supported by read-across of melting point values from similar substances cited in a reliable, authoritative secondary source, ranging from 2 to 25 °C at 101.325 kPa.
