CAS number: 84864-68-6
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
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
