Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
18 MAY 1998 - 18 MAY 1998
Reliability:
1 (reliable without restriction)
Reason / purpose:
reference to same study
Reason / purpose:
reference to other study
Qualifier:
no guideline required
Principles of method if other than guideline:
visual inspection
differential scanning calorimetry (DSC)
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Form:
other: wax-like
Colour:
colourless
Substance type:
organic
Conclusions:
The test item is colourless, wax-like mass.
Executive summary:

In a certificate of analysis, the phase-transition temperature is indicated from solid to liquid.

This is supported by the melting point study, where it is stated in the 'Presentation of the Test Item' that the appearance / physical state / colour is a colourless, wax-like mass. This was done by visual inspection.

In this study, the melting point of the test item was tested according to EU Method A.1 and OECD Guideline 102 in a non-GLP study. No exothermic effect was observed and the sample has a melting point of 51.4 °C (mean of two determinations).
