An
isotopically labelled compound is designated as selectively labelled when a mixture of
isotopically substituted compounds is formally added to the analogous
isotopically unmodified compound in such a way that the position(s) but not necessarily the number of each
labelling nuclide is defined. A selectively labelled compound may be considered as a mixture of
specifically labelled compounds.
