Density = (mass of sample x density of immersion liquid) / (mass of immersion liquid required to fill the empty pycnometer x mass of immersion liquid added to fill the pycnometer containing sample)
Mean result: 1304 kg.m-3 @ 20 degrees C
Description of key information
The relative density of 1,1"-isopropylidenediferrocene was determined to be 1.304.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.304
Additional information
The relative density of 1,1"-isopropylidenediferrocene was determined using a pygnometer and found to be 1.304.
The test was conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A3 and OECD Test Guideline 109.
