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:
1.358 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 s-1

Additional information

A study on phototransformation in air with the test substance is not available, but QSAR estimation with EPISuite program v.4.11 with the structural analogue, CAS 3001 -61 -4, was performed. A rate constant of 94.4876 E-12 cm³/molecule*sec and a half-life in the atmosphere of 1.358 hours for the substance was predicted by a calculation assuming a 24 hour day and an OH-radical concentration of 5.0E+05 molecules/cm³ (SRC AOP v1.92, 2017). However, the results must be concsidered cautiously since the substanc is a heterocyclic amine. Thus, estimation values are highly uncertain.
