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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

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
- 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:
- 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.

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.
