Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
until 1986-11-13
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
only summary and parts of the in general well-documented study report available
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
Guideline not stated but method description implies.
Deviations:
not specified
GLP compliance:
not specified
Type of method:
capillary method
Key result
Melting / freezing pt.:
>= 90 - <= 210 °C
Atm. press.:
ca. 1 013 hPa
Decomposition:
yes
Decomp. temp.:
50 °C
Remarks on result:
other: The test material appeared to break down with liberation of ammonia before the melting point was reached.
Conclusions:
Only summary and parts of the in general well-documented study report available, but given data indicate that the study was performed properly and the results are reliable.
Executive summary:

The melting range of the test item was determined using a capillary method with photocell detection and found to be 90 to 210°C. The test material appeared to break down with liberation of ammonia before the melting point was reached. The test material was found to be unstable at 50°C

Description of key information

Melting range (capillary method): 90 - 210°C, decomposition at 50°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
90 °C

Additional information
