Additional information

5 -Chlorovaleryl chloride is expected to rapidly hydrolyse in contact with water to form 5 -chlorovaleric acid (CAS 1119 -46 -6) and hydrogen chloride (CAS 7647 -01 -0). In a DOC-die away test 5 -chlorovaleryl chloride was readily biodegradable. No studies on the biodegradation of 5 -chlorovaleric acid are available. However, due to the rapid hydrolysis it is likely that the findings from the 8 -day study reflects the degaradation of the hydrolysis product 5 -chlorovaleric acid and it may thus be concluded that parent substance and the (organic) hydrolysis product are readily biodegradable.
