Description of key information

Tetraammine palladium (II) nitrate is only available on the market as an aqueous solution. 

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
liquid

Additional information

Tetraamminepalladium(II) nitrate is only brought on the market in solution (usually with 6-7% Pd content) because of the explosive properties of the solid form. The solvent can however be separated without affecting the chemical stability of the substance. A theoretical composition of the solid substance is included in the Composition section of the REACH dossier, but physico-chemical endpoints for this substance are completed based on the solution as marketed.

A statment on appearance and physical state of this substance has been provided by the registrant (Alderman 2016). This is considered to be suitable for use as a key study for this endpoint. Tetraammine palladium (II) nitrate is only available on the market as an aqueous solution. The substance is colourless and transparent liquid with ammonia-like odour.
