Description of key information

After evaporation or exposure to the air, the substance will be rapidly

degraded by photochemical processes.

Key value for chemical safety assessment

Additional information

The rate constant for the reaction of 2-dimethylaminoethyl methacrylate with hydroxyl radicals in the atmosphere was estimated by the SRC AOPWIN v1.92 program as 99.18 E-12 cm³/molecule*s. From this rate constant half-life for the reaction of OH radicals with the test substance is calculated as 3.9 hours assuming a 24h-day. Thus, after evaporation or exposure to the air, the substance will be rapidly degraded by photochemical processes.
