Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- 2012
- 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: Diferential Scanning Calorimetry
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 155.47 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The melting point of the test item was determined to be 155.47 ± 0.06 ºC.
- Executive summary:
A differential scanning calorimetry test (DSC) was performed to determine the melting point of the test item. Around 5 mg of test item were weighed in non-hermetic aluminium capsules and studied by differential scanning calorimetry over a temperature range extending from T = 293.15 K to the melting point temperature of the sample, with a heating rate of 1 K/min. All determinations were performed in a dry-nitrogen atmosphere. Based on the test results, the melting point of the test item is 155.47 ± 0.06 ºC.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
