Description of key information

After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes. 

Key value for chemical safety assessment

Additional information

According to a calculation N-vinylformamide is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life (t1/2) of about 18.1 hours taking into account a 24-h day and a mean OH radical concentration of 5.0 E05 radicals per cm³. The rate constant has been estimated as 21.28 E-12 cm³/(molecule*sec) at 25 °C (AOPWIN v1.92, 2008).
