Phototransformation in air

The substance has an estimated half-life in air of ~71 hours. As the cut-off time for reaching the stratosphere is 2 days, the substance is considered to have potential for reaching the stratosphere and/or long-range atmospheric transport. This assessment refers to dry air. In mist, rain, droplets and aerosols, hydrolysis will be the major fate process due to the short half-life in aqueous environments. Therefore assessment of the parent substance may be of low relevance.


The substance 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). Therefore, for all environmental compartments except air, available data on the environmental fate and pathways of the hydrolysis products is provided.
