1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
27 July 1995
Deviations:
no

yes
Type of method:
capillary method
Key result
Decomposition:
yes
Remarks:
The colour of the test substance changed to brown.
Decomp. temp.:
ca. 290 °C

The 3 repeat determinations of the melting temperature for the reference substance were: 236.1, 236.1 and 236.0°C. The mean melting temperature was 236.1°C.

This result demonstrates the reliability of the melting point apparatus.

Conclusions:
The test substance started to decompose at 290 °C.
Executive summary:

The melting point of the substance was determined in an experimental study under GLP conditions according to OECD Test Guideline 102. The determination of the melting temperature of the test substance was performed by the capillary method with hot block heating. Using this method it was determined that the test substance started to decompose at 290 °C.

Description of key information

The test substance started to decompose at 290 °C (reference 4.2 -1).

Key value for chemical safety assessment
