Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- October 2017
- 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-CoNa2 is technically not feasible as the test item decomposes before melting.
By replacing the sodium moiety of EDTA-CoNa2 by hydrogen the stability will not change significantly, 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)
- Type of method:
- differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- <= 178.47 °C
- Conclusions:
- The determination of the melting point of EDTA-CoNa2 is technically not feasible as the test item decomposes before melting.
The beginning of decomposition is state as 178.47 °C (451.62 K).
By replacing the sodium moiety of EDTA-CoNa2 by hydrogen the stability will not change significantly. Based on that it can be concluded that EDTA-CoH2 will not melt but decompose as well at or below 178.47 °C
