Environmental fate: 
Animals:Bromopropylate is rapidly and efficiently eliminated in animals. Metabolism occurs by cleavage of the isopropyl ester and, to a minor extent, by oxidation. Metabolites formed after oxidation were 3-hydroxybenzilate and conjugates.Soil:The principal metabolite in soil is 4,4-dibromobenzilic acid. For details of persistence in soil, see J. Environ. Qual., 1973, 2, 115. DT50 c. 40-70 d (lab. and field studies). Low mobility in Plant:Studies with 14C-labelled bromopropylate showed little penetration into leaves or fruit. Degradation was slow.
Transport Information
Signal Word:CAUTION; Hazard Class:III(Slightly hazardous)
