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:

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.
