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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Decomp. temp.:
- >= 155.86 °C
- Conclusions:
- Based on the study results it can be stated that decomposition of EDTA-NiH2 starts at 155.86 °C before melting.
- Endpoint:
- melting point/freezing point
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The determination of the melting point of EDTA-NiH2 is technically not feasible as the test item decomposes before melting.
By replacing the hydrogen moiety of EDTA-NiH2 by ammonia the stability will further decrease, so the determination will not be possible neither. - Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline

- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- no
- Type of method:

- Key result
- Decomp. temp.:
- >= 155.86 °C
- Conclusions:
- The determination of the melting point of EDTA-NiH2 is technically not feasible as the test item decomposes before melting.
By replacing the hydrogen moiety of EDTA-NiH2 by ammonia the stability will further decrease, so the determination will not be possible neither.
Based on the study results it can be stated that decomposition of EDTA-Ni(NH4)2 starts at or below 155.86 °C before melting.
