Additional information

No experimental data about the property for phototransformation in air are available. Although this is no mandatory requirement under REACH a scientifically accepted calculation method (EPIWIN computer tool AOPWINv1.92) was used to predict the overall OH rate constant (gas-phase reaction constant; which was determined to be 65.5296 E-12 cm³/molecules-sec) and the half-life (0.163 days; thus around 2 hours) for dimethylamine (Chemservice S.A., 2010). The substance is not supposed to react neither with ozone nor nitrate radicals.
