Description of key information

Key information:
Melting point (pour point) = -23 °C [Adams, 2012]
Further information:
1) Melting point/pour point = -20.15 ± 3.0 °C [Safepharm, 2007; Read-across data from C8 constituent];
2) Melting point/pour point = (37.6 ± 0.5 °C to 44.9 ± 0.5 °C) [Safepharm, 2007; Read-across data from C4 constituent];
3) Melting point = 186.5°C (459 K) [calculated for C9 constituent of isomeric mixture; EPIWIN, Chemservice S.A., 2011]

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-23 °C

Additional information

The melting point of the substance was not determined as its physical state at 20 °C and 1013 hPa is a liquid. The pour point of the test material is -23 °C as determined by the ASTM D97 guideline. The melting point of -20.15 of the "C8" subsatnce (CAS 144429 -84 -5) is close to the pour point of the target substance.
