Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- QSAR prediction
- Principles of method if other than guideline:
- The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).
- GLP compliance:
- no
- Type of method:

Description of key information
Methyl-N-{[dimethoxy(methyl)silyl]methyl}carbamate: 211.2 °C at 977.3 hPa (measured)
Key value for chemical safety assessment
Additional information
A measured boiling point value of 211.2°C at 977.3 hPa was determined for the parent substance according to EU Method A.2 (differential scanning calorimetry). This is supported by a boiling point value of 201°C at 1013 hPa obtained using an accepted calculation method (QSAR). The result is considered to be reliable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
