Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 03 January 2019 - 04 January 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 27 July 1995
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: pre-test to evaluate physical state
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Sponsor / 1702-18-01/O
- Expiration date of the lot/batch: 25 March 2021
- Purity test date: 26 March 2018
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room Temperature (20 ± 5 °C); Keep away from light
- Stability under test conditions: Stable
- Solubility and stability of the test substance in the solvent/vehicle: unknown - Key result
- Melting / freezing pt.:
- < -20 °C
- Decomposition:
- no
- Key result
- Melting / freezing pt.:
- < 253.15 K
- Decomposition:
- no
- Conclusions:
- In a pre-test, the test item 7-(4-ethyl-1-methyloctyl)quinolin-8-ol was still unfrozen and piercable at – 20 °C.
At -80 °C the test item was frozen. According to Regulation (EC) No 1907/2006 of the European Parliament and of the Council, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation the determination of the melting / freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted and the freezing point is stated as:
below - 20 °C (< 253.15 K).

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
