ABSTRACT:
A stabilized composition comprising an organic compound labeled with a .beta.-emitting radionuclide and a stabilizing effective amount of a non-radiolabeled stabilizing compound selected from the group consisting of (i) heteroaryls having at least one nitrogen atom, said heteroaryl being substituted with at least one sulfur-containing moiety selected from the group consisting of thiol and thiocarbonyl provided that the nitrogen atoms are not adjacent to one another; (ii) aryls being substituted with at least one nitrogen-containing moiety selected from the group consisting of amino and isothiocyanate and with at least one sulfur-containing moiety selected from the group consisting of sulfonamide, sulfonate, and thiol; and (iii) alkylamines having at least one to four carbon atoms, said alkylamine being substituted with at least one sulfur-containing moiety selected from the group consisting of thioacid and thiocarbonyl provided that when the sulfur-containing moiety is a thioacid then the aminoalkyl contains only one nitrogen atom.
