Conclusions:

Density of sodium hydrogen m-sulphonatobenzoate has been determined using the pycnometer method. As a result, the density of the test item was 1.7915 ± 0.0007 g/cm3 at 20 ± 0.2 °C. This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0003 g/cm3, showing very good correlation of the two determinations.

Executive summary:

The density of sodium 3-sulfobenzoate has been determined using the pycnometer method, according to OECD 109 and EU A.3. The measured density was 1.7915± 0.0007 g/cm³ at 20 ± 0.2 °C.
