key study
Study period:
April 16, 2014
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:
The test was performed according to the SOP - SRT 028 protocol.
GLP compliance:
no
Type of method:
thermal analysis
Remarks:
Differential Scanning Calorimetry
Decomposition:
yes
Decomp. temp.:
290 - 430 °C

The imbibition water/solvent release was observed between 25-130 °C, followed by decomposition of the product between 290 -430 °C (onset at 326.7 °C; enthalpy = 1931.4 J/g).

Conclusions:
The imbibition water/solvent release was observed between 25-130 °C, followed by decomposition of the product between 290 -430 °C (onset at 326.7 °C; enthalpy = 1931.4 J/g).
Executive summary:

Method

The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the Directive EC 440/2008 Method A.1. and according to the OECD Test Guideline 102 (1995).

Results

The imbibition water/solvent release was observed between 25-130 °C, followed by decomposition of the product between 290 -430 °C (onset at 326.7 °C; enthalpy = 1931.4 J/g).

Description of key information

Decomposition between 290 -430 °C
