Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Version / remarks:

no
Qualifier:
according to
Guideline:
EU Method A.3 (Relative Density)
Deviations:

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.
