Endpoint:
melting point/freezing point
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Justification for type of information:
As a preliminary test the sample was placed in a refrigerator whose cooling limit was -40°C. No solid formed after 3 days of storage under -40°C. The melting point was therefore below -40°C. According to Column 2 of REACH Annex VII, the study is not required and no actual determination was made.
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
Justification for type of information:
1-Butanol is the main hydrolysis prodcut of the target substance. Properties of 1-butanol are used for read-across.
Guideline:
other: not specified.
GLP compliance:
not specified
Type of method:
other: not specified
Key result
Melting / freezing pt.:
ca. -88.6 °C
Atm. press.:
ca. 1 atm
Conclusions:
The melting point of 1-butanol is -88.6°C under 1 atm according to lieterature.
Executive summary:

As the target substance hydrolyses rapidly the intrinsic properties are related to hydrolysis products of the target substance. This information is used as a supporting evidence on the toxicity of the target substance in CSA.

Description of key information

Melting point data of the hydrolyisis product 1 -butanol obtained from literature (handbook).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-88.6 °C

Additional information
