Melting point / freezing point
Administrative data
Link to relevant study record(s)
- 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. The substance only became unpourable but no solid formed after 3 days of starge 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. - Qualifier:
- according to guideline
- Guideline:
- other: in- house test
- GLP compliance:
- no
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Supplier: Borica Co., Ltd.
- Lot number: 110422Y
- Expiration date of the lot/batch: 2017-Dec-12
- CAS number: 101033-44-7 - Key result
- Melting / freezing pt.:
- < -40 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- Below -40°C.
- Executive summary:
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:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- 2-propanol is the main hydrolysis prodcuts of the target substance. Properties of the hydrolysis are used for read-across.
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- Not specified
- GLP compliance:
- not specified
- Type of method:
- other: not specified.
- Key result
- Melting / freezing pt.:
- ca. -90 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The freezing point of 2-propanol is -90°C according to literature.
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- ethanol is the main hydrolysis prodcuts of the target substance. Properties of the hydrolysis are used for read-across.
- Qualifier:

Description of key information
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -40 °C
Additional information
In a preliminary test in which the test substance was placed under -40°C and no freezing was observed. The melting point was therefore below -40°C. This value was used for CSA.
