EC number: 701-326-2 | CAS number: -
Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 2008-07-17 to 2008-12-18
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- The study was conducted similarly to guideline, with acceptable deviation. The substance is considered to be adequately characterised with its purity. Therefore validation applies, with restrictions.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- yes
- Remarks:
- closed crucible; single run
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Storage condition of test material: in a refrigerator at about 4°C.
- Key result
- Melting / freezing pt.:
- ca. 80 °C
- Decomposition:
- no
- Executive summary:
The test substance was investigated for explosive properties, including Differential Scanning Calorimetry screening test. Experimental conditions are acceptable for purpose.
The DSC trace shows a sharp endotherm, that can be interpreted as the melting temperature of the sample.
The melting point of the test substance is ca 80°C.
Reference
The DSC trace provided in the report shows a sharp endotherm peak, starting from about 70°C, with a maximum at about 85°C, and ending at about 90°C. The extrapolated onset temperature is expected to be ca 80°C.
Description of key information
Sharp melting transition expected at ca 80°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 80 °C
Additional information
A reliable study, conducted according to a recognized OECD/EU method is available. Despite restrictions due to test conditions, it is considered as a key study. The result is retained as key data for purpose of CSA.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
