- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 13 August 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)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 57 - ca. 222 °C
- Conclusions:
- Under the study conditions, melting point of the test substance could not be determined due to decomposition (57 - 222°C).
- Executive summary:
A study was conducted to determine the melting point of the test substance, C12-14 HEDMAC ( ≥ 90% active) using capillary method, according to the OECD Guideline 102 and EU Method A.1, in compliance with GLP. During the test, suspected decomposition of the test substance observed from approximately 57°C to 222°C (sample changed to translucent at 57.1°C followed by evolution of gas and rising of sample up the capillary tube). As a result, no further testing was performed. Under the study conditions, melting point of the test substance could not be determined due to decomposition (57 - 222°C) (Bee, 2019).

Result : 57 - 222°C Decomposition
Suspected decomposition observed from approximately 57°C to 222°C (sample changed to translucent at 57.1°C followed by evolution of gas and rising of sample up the capillary tube). As a result, no further testing was performed.
Description of key information
The melting point of the solvent-free test substance (≥ 90% active) was determined using capillary method, according to OECD Guideline 102 and EU Method A.1 (Bee, 2019).
Key value for chemical safety assessment
Additional information
No melting point could be determined, due to decomposition of the test substance between 57 - 222°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
