Description of key information

The test item is liquid from below or equal to 3.3 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
3.3 °C

Additional information

The melting range of the test item was determined according to OECD Guideline 102 and ASTM D3418-08 by differential scanning calorimetry.

The test item is a mixture of cis- and trans- isomers, typically in the concentration range of 30-40% cis- and 60-70% trans-, and is a liquid at ambient conditions. The trans- isomer also exists in two optical isomers, (1R)-trans- and (1S)- trans-.

Therefore, several endothermic effects were observed in the DSC curve (at -37.9 °C, -25.9 °C and at +3.3 °C).

It can be concluded that the test item is liquid from below or equal to 3.3 °C.
