Reference
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:
other: GLP compliant, guideline study, available as unpublished report, acceptable with restrictions
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
yes (incl. certificate)
Type of method:
differential scanning calorimetry
Melting / freezing pt.:
ca. 80 °C
Decomposition:
yes
Remarks on result:
other: No definitive signs of melting below 450°C

Authors state that as a result of the low rate of enthalpy change during decomposition, the onset temperature can only be approximated. Similar thermographic profiles were obtained using air and nitrogen atmospheres indicating decomposition is probably thermal and not oxidative.

Conclusions:
Tetraammineplatinum dichloride decomposed from approximately 80°C with no definitive signs of melting below 450°C.
Executive summary:

This is a GLP compliant, guideline study which is considered suitable for use as the key study for this endpoint. Tetraammineplatinum dichloride decomposed from approximately 80°C with no definitive signs of melting below 450°C.

Description of key information
