Additional information
In accordance with column 2 of REACH Annex VII, the melting/freezing point study does not need to be conducted below a lower limit of -20°C. Published data are available to show that the melting point of 2 -methylbut-2 -ene is -133.72°C and therefore testing of this endpoint was considered not to be needed.
No information on the primary source of the data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use for this endpoint. An earlier version of the source is used by OECD SIDS (2005) for this endpoint. The melting point of 2-methylbut-2-ene is -133.72°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
