Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
8-10 March 2004
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Guideline study, conducted to GLP. No reporting of impurity identification.
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
yes
Remarks:
Limited reporting detail - missing information on impurity content
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Version / remarks:
(of Directive 92/69/EEC)
Deviations:
yes
Remarks:
Limited reporting detail - missing information on impurity content
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Atm. press.:
1 008.4 hPa
Decomposition:
yes
Decomp. temp.:
200 °C
Remarks on result:
other: No melting, decomposes from approx. 200°C
Conclusions:
Platinum(II) tetraammine diacetate was determined by differential scanning calorimetry to decompose from 200 deg C, prior to melting.
Executive summary:

In a guideline-compliant study, conducted to GLP, the melting point of platinum(II) tetraammine diacetate could not be determined. The test substance was found by differential scanning calorimetry to decompose from 200 deg C, prior to melting.

Description of key information

Tetraammineplatinum(II) diacetate was determined to decompose at 200 deg C, prior to melting (Mekelburger, 2004a). 

Key value for chemical safety assessment

Additional information

The test item decomposed before melting occurred and therefore no melting point could be determined.
