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:
- Disodium 5-[[2,4-dihydroxy-5-[(4-nitrophenyl)azo]phenyl]azo]-4-hydroxy-3-[(2-hydroxy-3,5-dinitrophenyl)azo]naphthalene-2,7-disulphonate

- Disodium 5-[[2,4-dihydroxy-5-[(4-nitrophenyl)azo]phenyl]azo]-4-hydroxy-3-[(2-hydroxy-3,5-dinitrophenyl)azo]naphthalene-2,7-disulphonate
- Cas Number:
- 68155-63-5
- Molecular formula:
- C28H15N9Na2O16S2

Applicant's summary and conclusion
- Conclusions:
- Bioelimination based on TOC:
- 3 h: 8 % and 9 % at test substance concentration of 400 and 120 mgTOC/L respectively.
- 14 d: 23 % and 48 % at test substance concentration of 400 and 120 mgTOC/L respectively. - Executive summary:
Bioelimination based on TOC:
- 3 h: 8 % and 9 % at test substance concentration of 400 and 120 mgTOC/L respectively.
- 14 d: 23 % and 48 % at test substance concentration of 400 and 120 mgTOC/L respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
