Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method C.7 (Degradation: Abiotic Degradation: Hydrolysis as a Function of pH)
- Principles of method if other than guideline:
- Testing was carried out using a modified procedure as the test material is a solution in concentrated nitric acid for which a substance-specific analytical method was unavailable.
- GLP compliance:
- yes

- [Pt(NO3)x(OH)y]H2 where x = 2-5, y = 4-1, and x + y = 6
- IUPAC Name:
- platinum(4+) dihydrate tetranitrate
- Test material form:
- other: liquid
- Details on test material:
- The test material was in nitric acid and non-isolatable
Constituent 1
- Radiolabelling:
- no
Study design
- Analytical monitoring:
- no
- Details on test conditions:
- Aliquots of test material were diluted with glass double-distilled water, stored in a water bath at 50.0 +/- 0.5°C, and shielded from light.

- #1
Reference
- Reference substance name:
- Unnamed
- IUPAC name:
- hexahydroxy platinic acid
- Identifier:
- common name
- Identity:
- hexahydroxy platinic acid
- Details on hydrolysis and appearance of transformation product(s):
- Hydrolysis was assessed by visual estimation of the formation of hexahydroxy platinic acid, an orange-brown solid formed when the molar ratio of nitric acid to platinum in Platinum (VI) Nitrate is reduced below 8:1.
Dissipation DT50 of parent compound
- Temp.:
- 25 °C
- DT50:
- > 0 - < 1 d
- Remarks on result:
- other: at 4 times or greater dilution with water
- Details on results:
- Hydrolytic stability decreases with increasing dilution with water. At 4 times dilution or greater, the half-life is less than 1 day at 25°C.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- Hydrolytic stability decreases with increasing dilution with water. At 4 times dilution or greater, the half-life of Platinum (IV) Nitrate in nitric acid was less than 1 day at 25°C.
- Executive summary:
In a GLP, guideline study the half-life of Platinum (IV) Nitrate in nitric acid was less than 1 day at 25°C, at 4 times or greater dilution with water. This study is considered reliable and acceptable for use as key study for this endpoint.
