Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
October 9, 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Principles of method if other than guideline:
DSC analysis, performed according to internal protocol SOP - SRT 028.
GLP compliance:
no
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
> 245 - <= 374 °C
Sublimation:
no

Release of water/imbibition solvent occurs at ca. 90°C, followed by an exothermic decomposition between 245 and 374°C, with onset 280.3°C and enthalpy of -261.6 J/g.

Conclusions:
No melting up to 450°C; decomposition occurs between 245 and 374°C.
Executive summary:

Method:


The test was performed according to OECD guideline 102, using DSC analysis.


Result:


Release of water/solvent occurs at 90°C, followed by exothermic decomposition between 245 and 374°C.

Description of key information

OECD guideline 102 - No melting occurs between 25 and 450°C; the substance decomposes between 245 and 374°C.
