The half-life of (2-Ethoxy-1-methyl-2-oxoethyl)-5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate was estimated to be 32 h, with CO2 being the predominat degradation product
In the laboratory in artificial sunlight, (2-Ethoxy-1-methyl-2-oxoethyl)-5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate was predominantly degraded to carbon dioxide but also two products similar to those observed in soil metabolism studies. The substances were identified by TLC, GC/MS and other methods to be 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoyl-lactic acid and 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid. The half-life of the (2-Ethoxy-1-methyl-2-oxoethyl)-5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate was estimated to be 32 h as determined from the 14C activity suggesting that the trifluoromethyl-group carrying ring is degraded slightly faster than the other aromatic ring.
