Data on the stability of quinidine are only available for phototransformation. The calculated phototransformation of quinidine in air, calculated from the hydroxyl radical turn over rate is 160.1943 E-012 cm^3/molecule/s (0.00001384 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.
