other: Observation documented in the literature
Adequacy of study:
weight of evidence
Study period:
2008
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Principles of method if other than guideline:
Published value reported in the literature (handbook or collection of data).
GLP compliance:
not specified
Type of method:
method to determine freezing temperature
Melting / freezing pt.:
> 25 °C
Atm. press.:
1 atm
Remarks on result:
other: > 25 °C or > 298 K
Conclusions:
The melting temperature of the test item has been reported in the literature to be greater than 298 K (or > 25 °C) (quoted value: 42.8 °C).
Executive summary:

The melting/freezing temperature is reported in the literature (Lide, D.R. CRC Handbook of Chemistry and Physics 86TH Edition 2005-2006. CRC Press, Taylor & Francis, Boca Raton, FL 2005. Also cited in : MPBPv1.43, US EPA (via PHYSPROP)). The melting temperature of the test item is reported to be greater than 298 K or greater than 25 °C at 1 atmosphere pressure (quoted value: 42.8 °C).

Description of key information

MP: > 298 K (> 25 °C) at 1 atm, weight of evidence approach, 1975 and 2008.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
42.8 °C

Additional information

Weight of evidence approach, 1975 and 2008: The melting/freezing temperature is documented in published literature (handbooks/data-tables). The melting temperature of the test item has been reported to be greater than 298 K or greater than 25 °C at 1 atmosphere pressure (reported melting point 42.8 - 43.8 °C).
