Batch no. 170103
CAS No. 17625-03-5
Purity > 99.0% (Titration with NaOH, Glass indicating electrode, Calomel reference electrode)
Expiry date 14. Feb. 2019
Storage Room Temperature (20 ± 5°C), keep away from humidity - Type:
- relative density
- Density:
- 1.792 other: dimensionless, since it is a relative density
- Temp.:
- 20 °C
- 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.
