- Melting / freezing point at 101 325 Pa:
- 450 °C
Additional information
Walker and White (2011) is a GLP compliant, guideline study which is considered suitable for use as the key study for this endpoint. Palladium (II) di(4-oxopent-2-en-2-oate) decomposed from approximately 180 °C (453K), with no definitive signs of melting below 450 °C (723K).
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. Palladium (II) 2,4 -pentanedioate decomposes before melting. The decomposition temperature is 205°C.
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).
