melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2007-06-12
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods
Reason / purpose:
reference to same study
Qualifier:
no guideline available
Principles of method if other than guideline:
The solid state was determined by X-ray Powder Diffractometry and by Differential Scanning Calorimetry (DSC) according to an internal test method using .
GLP compliance:
not specified
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
ca. 70 °C

The obtained diffraction spectra and DSC thermograms do not show any significant differences. The DSC thermograms of all analyzed samples showed one sharp peak, indicating the melting of the substance at about 70°C.

Conclusions:
A melting point value of about 70°C was obtained from a differential scanning calorimetry (DSC) study.

Description of key information

A melting point of about 70°C was determined by differential scanning calorimetry (DSC).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
