- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E 537
- Deviations:
- no
- Principles of method if other than guideline:
- Differential Thermal Analysis (DTA) records the difference of the temperature of a substance and an empty measuring cell. The substance and reference cell were subjected to the same controlled temperature program. The sample (trial 1: 11.6 mg (Mz. 15), trial 2: 13.5 mg (Mz. 16) and trial 3: 12 mg (Mz. 17)) was heated in a glass vessel at a linear rate of 1 K/min up to 20 °C. The measurement was recorded electronically.
- GLP compliance:
- yes
- Type of method:
- thermal analysis
- Remarks:
- Differential Thermal Analysis (DTA)
- Specific details on test material used for the study:
- Batch number: 20140202
Content: 98.6 %
Physical condition: clear colorless liquid
Expiration date: 2030-12-09
Storage: Room temperature - Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: There is no melting point down to -35°C.
- Conclusions:
- 2,2,4-Trimethyl-1-oxa-4-aza-2-silacyclohexane shows no melting point down to -35°C.
- Executive summary:
2,2,4-Trimethyl-1-oxa-4-aza-2-silacyclohexane shows no melting point down to -35°C.
The Differential Thermal Analysis (DTA) was used.
Analysis was carried out according to (EC) No 440/2008 A.1 (ASTM E 537).
Reference
There are no endothermic effects in the temperature range from -35°C to 20°C which indicated a melting.
