key study
Study period:
2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
July 27, 1995
Deviations:
no

no
Qualifier:
according to guideline
Guideline:
EPA OPPTS 830.7200 (Melting Point / Melting Range)
Version / remarks:
March 1998
Deviations:
no
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
> 125 °C
Remarks on result:
not determinable
Remarks:
Melting of the test item was not observed below the temperature at which reaction and/or decomposition started
Conclusions:
The melting and boiling temperature of Reaction mixture of CuDTPA and CuHEEDTA were tested by DSC.
Reaction and/or decomposition of the test item was observed during DSC experiment at temperatures of > 125°C (> 398 K). Melting 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 temperature.

Description of key information

The melting point could not be determined because decomposition occurred at temperatures above 125°C

Key value for chemical safety assessment
