Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
26 April 2006

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 109 (Density of Liquids and Solids)
Deviations:
yes
Remarks:
Limited reporting detail - missing information on impurity content
Qualifier:
according to
Guideline:
EU Method A.3 (Relative Density)
Version / remarks:
(of Directive 92/69/EEC)
Deviations:
yes
Remarks:
Limited reporting detail - missing information on impurity content
GLP compliance:
yes
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
pycnometer method
Type:

 Mean value of density        2.1206  g/cm3

Relative density (D420) is 2.1206  g/cm3/ 0.9997  g/cm3 (density of water at 4 deg C) = 2.1207  g/cm3

Conclusions:
The relative density of platinum(II) tetraammine diacetate at 20 deg C was determined to be 2.1207.
Executive summary:

In a guideline study, conducted to GLP, the relative density of platinum(II) tetraammine diacetate was determined by the pycnometer method to be 2.1207 at a temperature of 20 deg C.
