Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2008-11-07

Reliability:

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.7.1.2.1”.

GLP compliance:

no

Type of method:

method to determine freezing temperature

Key result

Melting / freezing pt.:

< -20 °C

Atm. press.:

101.3 kPa

Conclusions:

Melting point: below 253 K (-20 °C)

Executive summary:

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).

Description of key information
