Materials and methods
- Principles of method if other than guideline:
- - Principle of test: Dynamic mechanical analysis (DMA)
- Short description of test conditions: DSC was first used to try to determine the freezing point. However, no freezing was seen. Therefore for DMA was used.
- Parameters analysed / observed: Crystallization of the material - GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- differential scanning calorimetry
Test material
- Reference substance name:
- 6-Hydroxy-2,6-dimethylheptan-1-al
- Cas Number:
- 62439-42-3
- Molecular formula:
- C9H18O2
- IUPAC Name:
- 6-Hydroxy-2,6-dimethylheptan-1-al
- Test material form:
- liquid
Constituent 1
Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- -51 °C
- Atm. press.:
- 760 Torr
- Decomposition:
- no
Applicant's summary and conclusion
- Conclusions:
- The freezing point is -51 degrees C.
- Executive summary:
The freezing point of the test substance was determined. The first method used to try to determine the freezing point was DSC. However, no crystallization was seen. DMA was then used. An increase of viscosity was taken as the freezing point. Based on extrapolation the freezing point was -51 degrees C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
