Description of key information

Dihydrogen hexahydroxyplatinate decomposes before it melts. The decomposition temperature is ~ 145°C

Key value for chemical safety assessment

Additional information

Walker & White (2011) study is a GLP complaint, guideline study considered suitable for use as the key study for this endpoint. The decomposition temperature of dihydrogen hexahydroxyplatinate is approximately 145 °C with no definitive signs of melting below 450°C

The CRC Handbook (Lide, 2008) is a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the supporting study for this endpoint. The decomposition temperature is 100 °C.
