Details on results:
The chromatogramm of the test item gave two peaks when detecting at 228 nm, but only one peak at 256 nm. The main peak had a retention time of 2.726 min (mean of 3 experiments). A small peak was visible at 228 nm only and was considered as not relevant. The NMR data of the test item showed that the test item is a pure substance. Therefore only the main peak was evaluated.
