Conclusions:
Palladium (II) di(4-oxopent-2-en-2-oate) (anhydrous solid) is a yellow powder.
Executive summary:

Information on the appearance of palladium (II) di(4 -oxopent-2 -en-2 -oate) is from a Klimisch 1 GLP compliant guideline experimental study. The statement on appearance is taken from a study on physico-chemical properties of this material, and is adequate for the assessment as the key study for this endpoint. Palladium (II) di(4-oxopent-2-en-2-oate) (anhydrous solid) is a yellow powder.

Description of key information

Palladium (II) di(4-oxopent-2-en-2-oate) (anhydrous solid) is a yellow powder.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
solid

Additional information

Walker and White (2011) is a Klimisch 1, GLP-compliant study. The statement on appearance is taken from a study on physico-chemical properties of palladium (II) di(4-oxopent-2-en-2-oate), and is adequate for assessment as the key study for this endpoint. Palladium (II) di(4-oxopent-2-en-2-oate) (anhydrous solid) is a yellow powder.

The CRC Handbook (Lide 2008) is a reliable peer reviewed handbook and so can be considered reliable and suitable for use as a supporting study for this endpoint. At 20ºC and 1013.25 hPa palladium (II) 2,4-pentanedioate forms orange yellow crystals.
