- 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
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- yes
- Remarks:
- Limited reporting detail - missing information on impurity content
- Qualifier:
- according to guideline
- 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.
Reference
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.
