Administrative data

Endpoint:
melting point/freezing point
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Study period:
05 Feb 2005 (first data acquisition), 01 Apr 2005 (final data acquisition).
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP-guideline study, tested with the source substance CAS 1318-02-1. According to the ECHA Guidance Document "Practical guide 6: How to report read-across and categories (March 2010)", the reliability was changed from RL1 to RL2.

Results and discussion

Melting / freezing point
Melting / freezing pt.:
> 400 °C

Any other information on results incl. tables

The thermograms displayed only a falling baseline, with no significant endotherms or exotherms. It is concluded that this material does not undergo melting, boiling or decomposition in the temperature range 20 to 400°C.
