Description of key information

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

Key value for chemical safety assessment

Half-life in air:
9.149 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 s-1

Additional information

Based on a 24 -h day and an OH-radical concentration of 0.5 E06 OH/cm³, a degradation rate constant of 42.09 E-12 cm³/(molecule*sec) was estimated for cyclopentylamine (CAS 1003 -03 -8) by the EPISUITE model AOP v1.92. Following this, the substance is expected to be photodegraded by OH-radicals with a half-life of 9.149 h or 0.381 d, respectively (BASF, 2013).

Hence, the test substance is expected to be rapidly degraded by photochemical processes after evaporation or exposure to air.
