Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

No relevant repeated dose toxicity data were identified for platinum dinitrate. However, good support for the conclusion that a repeated dose toxicity study can be waived comes from two sources. Firstly, a consideration of the known toxicity and physico-chemical properties of this compound. Platinum dinitrate is a strong acid (pH<2.0) and exhibits skin corrosivity in vitro. Secondly, there are good-quality endpoint-specific data on another platinum (IV) species. In a combined repeated-dose and reproductive/developmental toxicity screening test, no adverse effects were observed at daily doses of hexahydroxyplatinic acid up to 1000 mg/kg bw/day. This supports the hypothesis that, even if testing were possible, platinum dinitrate would not be expected to cause any significant systemic toxicity.

Mode of Action Analysis / Human Relevance Framework

No data identified.

Additional information

No relevant human data were identified. However, consideration of the known toxicity and physico-chemical properties of this compound, as well as good-quality endpoint-specific data on another platinum (IV) species, provides good support for the conclusion that a repeated dose toxicity study can be waived.

 

As platinum dinitrate is a strong acid and exhibits skin corrosivity in vitro, repeated dose testing by the oral route is not considered scientifically justified.
