Conclusions:
Dicarbonyl(pentane-2,4-dionato-O,O')rhodium has a median particle size d(0.5) = 4.572 µm.
Executive summary:

This study does not follow a standard guideline, but particle size distribution was assessed using a particle size analyser and this is considered suitable for use for this endpoint. Dicarbonyl(pentane-2,4-dionato-O,O')rhodium has a median particle size d(0.5) = 4.572 µm, as determined by a particle size analyser.

Description of key information

Dicarbonyl(pentane-2,4-dionato-O,O')rhodium has a median particle size d(0.5)of 4.572 µm.

Additional information

Michael-Schulz (2012) does not follow a standard guideline, but particle size distribution was assessed using a particle size analyser and this is considered suitable for use for this endpoint. Dicarbonyl(pentane-2,4-dionato-O,O')rhodium has a median particle size d(0.5) of 4.572 µm.
