Administrative data

Endpoint:
boiling point
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid which decomposes before boiling
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information
Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
07/04/2020 to 22/06/2020
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)
Qualifier:
according to guideline
Guideline:
EPA OPPTS 830.7200 (Melting Point / Melting Range)
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Key result
Decomposition:
yes
Decomp. temp.:
125 °C
Conclusions:
The melting temperature of MEAHA-Na were tested by DSC.
Reaction and/or decomposition of the test item was observed during DSC experiment starting at 125°C (398K). Melting and/or boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no melting and/or boiling temperature.
Executive summary:

The melting temperature of MEAHA-Na were tested by DSC.

Reaction and/or decomposition of the test item was observed during DSC experiment starting at 125°C (398K). Melting and/or boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no melting and/or boiling temperature.
