Test material
- Reference substance name:
- (6S)-4,5,6,7-tetrahydro-1,3-benzothiazole-2,6-diamine 2,3-dihydroxybutanedioic acid trihydrate
- EC Number:
- 928-472-1
- Cas Number:
- 1184301-52-7
- Molecular formula:
- C11-H17-N3-O6-S x 3H2O
- IUPAC Name:
- (6S)-4,5,6,7-tetrahydro-1,3-benzothiazole-2,6-diamine 2,3-dihydroxybutanedioic acid trihydrate
- Test material form:
- solid: particulate/powder
Constituent 1
- Specific details on test material used for the study:
- In the study report is mentioned that a dihydrate was used for testing, this statement is not correct. After further evaluation of the substances it was found out that it is a trihydrate. The batch for testing was a typical production batch.
Results and discussion
Surface tension
- Key result
- Surface tension:
- 71.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
Applicant's summary and conclusion
- Conclusions:
- The surface tension of SND 919 Precursor 3a ((-)-SND 855 Tartrate) aqueous solution (1g/l) was found to be 71.4 mN/m at 20°C using the ring method. As this value is higher than 60 mN/m SND 919 Precursor 3a ((-)-SND 855 Tartrate) is classified as not surface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
