Materials and methods
- Principles of method if other than guideline:
- The bioelimination of the substance was evaluated in a test based on determination of organic carbon (TOC), according to an internal method. Two substance concentrations were tested and the elimination % was evaluated in a 14-day study period.
- GLP compliance:
- no
- Type of study / information:
- Determination of organic carbon (TOC)
Test material
- Reference substance name:
- Trisodium 4-amino-5-hydroxy-3-[[4-[[2-oxo-1-[(phenylamino)carbonyl]propyl]azo]phenyl]azo]-6-[(4-sulphonato-1-naphthyl)azo]naphthalene-2,7-disulphonate
- EC Number:
- 279-093-7
- EC Name:
- Trisodium 4-amino-5-hydroxy-3-[[4-[[2-oxo-1-[(phenylamino)carbonyl]propyl]azo]phenyl]azo]-6-[(4-sulphonato-1-naphthyl)azo]naphthalene-2,7-disulphonate
- Cas Number:
- 79135-92-5
- Molecular formula:
- C36H25N8Na3O12S3
