Administrative data
Link to relevant study record(s)
- Endpoint:
- thermal stability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- October 2009
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Comparable to guideline study (OECD113) with acceptable restrictions
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- The thermal stability of a substance was determined using Difference Scanning Calorimetry (DSC). Therefore, some milligrams of the substance were weighed into a glass crucible which was fused by an oxyhydrogen flame.
- GLP compliance:
- no
- Specific details on test material used for the study:
- Manufactured by the Subimitter,
Batch number B 526734
Purity > 95% - Test substance thermally stable:
- no
- Key result
- Operating temp.:
- > 25 - < 400 °C
- Sublimation:
- not determined
- Transformation products:
- not measured
- Conclusions:
- The differential scanning calorimetry in a closed glass crucible showed a plausible decomposition signal in the temperature range of 194.26°C - 283.71 °C with a decomposition energy of 260.83 J/g.
- Executive summary:
The differential scanning calorimetry in a closed glass crucible showed a plausible decomposition signal in the temperature range of 194.26°C - 283.71 °C with a decomposition energy of 260.83 J/g.
- Endpoint:
- thermal stability
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 15 July 2019
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263
- Principles of method if other than guideline:
- A Grewer Oven test and an 8h-long-term-stability test were performed.
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- Manufactured by the Subimitter,
Batch number B 526734
Purity > 95% - Test substance thermally stable:
- yes
- Conclusions:
- The temperature of onset of temperature raise in airstream was 231 °C (Peak Maximum) in the Grewer test.
The 8h+8h long-term-stability temperature (LZT) was 160 °C. - Executive summary:
The 8h long-term-stability temperature (LZT) was 160 °C.
