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

Half-life in air:
3.97 h

Additional information

There is an AOP v1.92 calculation available for the estimation of the photodegradation in the atmosphere. For this calculation a 24 -hour day as well as a sensitizer-concentration (OH-radicals) of 500,000 molecules/cm³ were assumed.

The calculated rate constant is 9.69546E-11 cm³/molecule-sec results in a half-life in the atmosphere of 3.97 hours. As the substance is a tertiary amine, the estimate may be highly uncertain according to the description of the applicability domain.
