Can the bond between Morpholine and Benzene be broken and hence morpholine nitrosated to N-nitroso Morpholine?
I believe that the answer in this case is, in case of doubt, do a Nitrosation assay.
In my opinion, the risks comes more from phenylmorpholine containing certain amounts of morpholine as impurity which can be nitrosated rather than direct nitrosation of phenylmorpholine
