Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

06 Jul 2016

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Principles of method if other than guideline:

- Principle of test: Melting point is determined by the use of differential scanning calorimetry (DSC) in which the difference in the amount of heat required to increase the temperature of a sample and
reference is measured as a function of temperature.
- Short description of test conditions:
 Fill a DSC pan with ± 1 to 5mg sample and record the sample weight
 Close the DSC sample pan with a pan cover using a pan press
 Place the sample pan into the sample position of the DSC
 Prepare an empty reference pan and place it into the reference position of the DSC
 Start the analysis

GLP compliance:

not specified

Type of method:
