Reference

Reference 1

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Not reported

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: GLP status not known, guideline not known, information from published handbook, data compendium, review article or other reference text, acceptable with restrictions

Principles of method if other than guideline:

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of physico-chemical data.

GLP compliance:

not specified

Physical state at 20°C and 1013 hPa:

solid

Additional information

The statement on appearance is taken from the test substance identity section of a Klimisch 1, GLP-compliant study on physico-chemical properties (Tremain and Atwal 2011). This is considered to be suitable for use as the key study for this endpoint. 

Supporting information is taken from a reliable peer reviewed handbook (Lide 2008) and can be considered reliable and suitable for use for this endpoint. At 20°C and 1013.25 hPa ammonium hexachloropalladate forms red-brown hygroscopic crystals.
