Materials and methods

Principles of method if other than guideline:
The substance was placed in 247 K (-26 °C) for approximately 24 h and was then visually examined. As it was still in a liquid phase, it was concluded that the substance has a melting point below 253 K (-20 °C) and is therefore not applicable according to “Endpoint specific guidance R.7.1.2.1”.
GLP compliance:
no
