Description of key information

Further test on melting point does not need to be conducted as the melting point of the substance is below -20°C. The melting point of the test item was reported to be -33.15 °C at 1013.25 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-33.15 °C

Additional information

In accordance with column 2 Annex VII section 7.2 of Regulation (EC) No 1907/2006 (REACH), the test on melting point does not need to be conducted as the melting point of the substance is below -20°C. In addition a literature review was conducted. In a weight of evidence approach the literature values were evaluated. The NIST Chemistry WebBook (NIST, 2014) reports the melting point to be -33.15 °C. The CRC Handbook of Chemistry and Physics 88th Edition (2008) reports the melting point to be -34 °C and the GESTIS Database (GESTIS, 2014) reports the melting point to be -34.6 °C. The NIST Webbook was regarded as most reliable literature source and -33.15 °C was therefore chosen as key value for chemical safety assessment.
