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:
- 30 Jan 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Melting / freezing pt.:
- < -100 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- A melting point value of <-100 °C at 1013 hPa was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.

Mean value: |
< –100 °C (<173 K) |
The DSC diagrams show no freezing temperature (no exothermic peak) and no melting temperature (no endothermic peak) which is higher than –100°C (173 K).
There was no indication of any discernible decomposition in the diagrams.
Description of key information
Diethoxy(methyl)silane: < -100 °C at 1013 hPa (DSC method, EU Method A.1)
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
