melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Preliminary study
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.”.
GLP compliance:
Type of method:
method to determine freezing temperature
Melting / freezing pt.:
< -20 °C
Atm. press.:
101.3 kPa
Melting point: below 253 K (-20 °C)
Executive summary:

Melting point: below 253 K (-20 °C)
