Description of key information
Biodegradability of (2E)-3-phenylprop-2-en-1-yl butanoate (CAS: 103-61-7 ) is predicted using OECD QSAR toolbox version 3.3 with log Kow as the primary descriptor. Test substance undergoes 87.2 % degradation by BOD in 28 days. Thus, based on percentage degradation, the test chemical (2E)-3-phenylprop-2-en-1 -yl butanoate (CAS: 103-61-7 ) was estimated to be readily biodegradable in water
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Following studies include the predicted data for the target chemical to conclude the extent of(2E)-3-phenylprop-2-en-1-yl butanoate (CAS: 103-61-7) towards
Biodegradability in water is summarized as follows:
Biodegradability of (2E)-3-phenylprop-2-en-1-yl butanoate (CAS: 103-61-7 ) is predicted using OECD QSAR toolbox version 3.3 with log Kow as the primary descriptor. Test substance undergoes 87.2 % degradation by BOD in 28 days. Thus, based on percentage degradation, the test chemical (2E)-3-phenylprop-2-en-1 -yl butanoate (CAS: 103-61-7 ) was estimated to be readily biodegradable in water.
Similar estimated data is from the Estimation Programs Interface Suite (EPI suite, 2017) was run to predict the biodegradation potential of the test compound Cinnamyl butyrate (CAS no.103 -61 -7) in the presence of mixed populations of environmental microorganisms. The biodegradability of the substance was calculated using seven different models such as Linear Model, Non-Linear Model, Ultimate Biodegradation Timeframe, Primary Biodegradation Timeframe, MITI Linear Model, MITI Non-Linear Model and Anaerobic Model (called as Biowin 1-7, respectively) of the BIOWIN v4.10 software. The results indicate that chemicalCinnamyl butyrateis expected to be readily biodegradable.
The predicted data for the target chemical is supported by the structurally simislar read across Dimethyl terephalate (CAS: 120 -61 -6) data is from the J-Check also indicates that the Biodegradation in water test was carried out for Dimethyl terephthalate according to the OECD Guideline 301 C (Ready Biodegradability: Modified MITI Test (I)) Dimethyl terephthalate (CAS : 120-61-6) is readily biodegradable after 14 days (120h). After 14 days (120h) the maximum % degradation is 84%.
Further it is supported by another structurally similar read across Dimethyl phthalate (CAS: 131 -11 -3) data is from the publication Applied and Environmental Microbiology 1984, An acclimated shake flask CO2 evolution test was used to study the biodegradability of Dimethyl phthalate.
Dimethyl phthalate (CAS : 131-11-3) is readily biodegradable after 28 days . After 28 days the maximum % degradation is >99%.
