After the respective reaction time, the triplicate tubes were removed from the reactor and the solution in each tube was split into three subsamples: 100 µL were taken for high pressure liquid chromatography with charged aerosol detection and high-resolution mass spectrometry (HPLC-CAD-HR-MS) analysis, 900 µL were taken for 13 C-NMR analysis, and 7 mL for the biodegradability testing. Details on the analytical methods are provided in section S2
