- Conclusions:
- The relative density of 2-Anthracenesulfonic acid, 9,10-dihydro-9,10-dioxo-, sodium salt (1:1) was determined to be 1.660 at 20°C.
- Executive summary:
The relative density of 2-Anthracenesulfonic acid, 9,10-dihydro-9,10-dioxo-, sodium salt (1:1) was determined to be 1.660 (mean value of two determinations) at 20°C. The analysis was based on OECD Guidelines for Testing of Chemicals, Section 1 – Physical-Chemical Properties No: 109. Principle of the test is displacement method.
