according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Deviations:

GLP compliance:

Type of method:

differential scanning calorimetry

Key result

Decomposition:

yes

Decomp. temp.:

> 360 °C

Between 25 - 150 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a exothermic peak related to degradation starting from 360 °C.

Conclusions:

No melting point detected up to 440 °C

Executive summary:

Method

The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.

Result

Between 25 - 150 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a exothermic peak between 252 and 321 °C (onset at 259 °C, enthalpy = 13.7 J/g) followed by the degradation of the product starting from 360 °C.

Description of key information

The substance decomposes before melting/boiling from 360 °C

Key value for chemical safety assessment

Additional information

The melting point analysis was performed according to internationally accepted testing guidelines, using the Differential Scanning Calorimetry (DSC) method for the analysis. Between 25 - 150 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a exothermic peak between 252 and 321 °C followed by the degradation starting from 360 °C.
