Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Principles of method if other than guideline:
- Experimental measurement (data is taken from a reliable handbook, information about the methodology is not available)
- GLP compliance:
- not specified
- Type of method:
- other: Not stated
- Key result
- Melting / freezing pt.:
- -113.6 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- ambiguous
- Sublimation:
- no
- Remarks on result:
- other: 1013 hPa assumed
- Conclusions:
- A melting point value of -113.6°C was reported for the substance in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.
Reference
The melting point obtained from the DIPPR 801® Database is recognized by the AIChE as the accepted melting point for trimethoxysilane and is comparable to values from other sources. The AIChE DIPPR 801 Database specifies that the uncertainty associated with the melting point value for trimethoxysilane is < 1%.
Description of key information
Melting point: -113.6°C at 1013 hPa
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -113.6 °C
Additional information
A melting point value of -113.6°C at 1013 hPa was reported for the substance in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable and selected as key study.
In other available secondary sources to which reliability could not be assigned, melting point values of -115°C, -114.8°C and -114°C were reported for the substance.
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.
