Description of key information

The calculated phototransformation of quinic acid in air, calculated from the hydroxyl radical turn over rate is almost zero.

Key value for chemical safety assessment

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

Additional information

The calculated phototransformation in air, calculated from the hydroxyl radical turn over rate is 40.6288 E-012 cm^3/molecule/s (0.00000351 cm^3/molecule/d). Therefore, we consider phototransformation in air to be negligible. These results are calculated using AOP v1.92, expecting, that phototransformation appears at a constant rate. The EPA recommends that empirical measures provide better results. However, empirical studies have not been done, so that we adapt the prediction.
