Biodegradation in water:
Prediction model based estimation and data from read across (CAS no 8004 -92 -0) are used to determine the biodegradation potential of the test compound CAS no 84864 -68 -6. The summary is as follows:
The test compound sodium 2-(2 3-dihydro-1 3-dioxo-1H-inden-2-yl)quinoline-6-sulphonate (CAS no 84864 -68 -6) is not readily biodegradable (Estimation Programs Interface Suite, 2016).
Short term aerobic biodegradation study was conducted by Pagga et al, 1986 for the test material Acid yellow 3 (RA CAS no 8004 -92 -0). Readily water-soluble dyestuff acid yellow 3 was subjected to modification of the OECD Guideline 302B of the static test method. 100 mg/L dyestuff was tested with 0.5 mg/L activated sludge for inherent biodegradtion for upto 42 days. The feeding used for inoculums was 100 mg/L yeast extract every week. Extinction at absorption maximum and DOC (dissolved organic carbon) were the parameters included in the study. The test compound Acid yellow 3 showed -44% DOC removal suggesting that it is not biodegradable under the mentioned test conditions.
The above data suggest that the target test chemical sodium 2-(2 3-dihydro-1 3-dioxo-1H-inden-2-yl)quinoline-6-sulphonate is likely not to be biodegradable.
