The mean density of the test item at 20 °C is 1.5242 g/cm³. The relative density D420is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).
The relative density is D420=1.524.
Applicant's summary and conclusion
- Conclusions:
- The relative density of 4-Chlorobenzoic acid is 1.524 as determined via the pycnometer method.
- Executive summary:
According to OECD Test Guideline 109 (2012), Regulation (EC) No 440/2008 Method A.3. and EPA OCSPP Test Guideline OPPTS 830.7300 (2002), the Relative Density D420 of the test item para-Chlorobenzoic acid at 20 °C ± 0.01 °C (compared to water at 4 °C) is determined to be:
D420 = 1.524
