Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- supporting study
- Study period:
- 2001
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The main study was not conducted as preliminary tests indicated that no freezing process occurs under the given conditions.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- not specified
- Type of method:
- method to determine freezing temperature
- Melting / freezing pt.:
- < -50 °C
- Conclusions:
- In conclusion, the freezing point range of 3-methoxy-3-methyl-butan-1-ol is < -50°C (<223 K).
- Endpoint:
- melting point/freezing point
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:

Description of key information
Melting/freezing point: < -50°C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
Freezing point ranges of < -50°C are reported in a reliable study conducted according to an appropriate test protocol.
In accordance with Column 2 of REACH Annex VII, the melting point study does not need to be conducted below a lower limit of -20°C. The existing data is sufficient to indicate a melting point well below this temperature.
