EC number: 204-646-6 | CAS number: 123-72-8
Melting point / freezing point
Administrative data
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2008-11-07
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: guideline recommendations - According to “Endpoint specific guidance R.7.1.10.1” the test does not need to be conducted if the melting/freezing point is below -20 °C.Futher study is scientifically unjustified after a preliminary test.
Data source
Reference

Materials and methods
Test guideline
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- The substance was placed in 247 K (-26 °C) for approximately 24 h and was then visually examined. As it was still in a liquid phase, it was concluded
that the substance has a melting point below 253 K (-20 °C). - GLP compliance:
- no
- Type of method:
- other: freezer at -26°C

- Cas Number:
- 123-72-8
- Molecular formula:
- C4H8O
- IUPAC Name:
- butanal
- Test material form:
- liquid
- Details on test material:
- - Name of test material (as cited in study report): n-Butyraldehyde

Constituent 1
Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- 101.3 kPa
Applicant's summary and conclusion
- Conclusions:
- Melting point/freezing point: < 253 K (< -20 °C)
- Executive summary:
Melting point/freezing point: < 253 K (< -20 °C)
Futher study is scientifically unjustified after a preliminary test.
According to “Endpoint specific guidance R.7.1.10.1” the test does not need to be conducted if the
melting/freezing point is below -20 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
