Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For platinum dinitrate, data are read across from another platinum(IV) substance without a chloro ligand, dihydrogen hexahydroxyplatinate. The 48-hour EC50 was calculated to be 0.481 mg Pt L-1.
Key value for chemical safety assessment
Additional information
For platinum dinitrate, data are read across from another platinum(IV) substance without a chloro ligand, dihydrogen hexahydroxyplatinate.
A 48-h acute immobilisation Daphnia magna study is available for Dihydrogen hexahydroxyplatinate following OECD guideline 202 and EU Method C.2.8 (Simon 2014). A semi-static test system was followed, where test solutions were renewed after 24 hours, and fresh and aged test solutions were analysed at the start and at each renewal until the end of the test using ICP-OES. Five test concentrations were used. Analysis of fresh and aged exposure media revealed significant decreases of the test item within the 24-hour interval, therefore results were based on average time weighted mean concentrations. All validity criteria were met. An extrapolated 48-hour EC50 was calculated to be 0.742 mg test item L-1 (0.481 mg Pt L-1). The 48-hour NOEC was determined to be ≥ 0.572 mg test item L-1 (≥ 0.37 mg Pt L-1).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
