Disclosed are methods for manufacturing radiohalogen-labeled steroids, nucleosides, nucleotides and proteins, for example, pyrimidines and proteins. Methods according to the example embodiments specific to pyrimidines includes dissolving a halogenated pyrimidine to obtain an initial solution, adding bis(tributyltin) and triphenylphosphine palladium to produce a catalyzed solution, heating the catalyzed solution under conditions sufficient to induce a reaction that produces an intermediate solution including a stannylated pyrimidine compound, removing substantially all of the first solvent from the intermediate solution to obtain an intermediate composition, purifying the resulting solution to obtain a purified composition including a stannylated pyrimidine, reacting the stannylated pyrimidine compound with a radiohalogen in a buffered reaction mixture to produce the radiohalogenated pyrimidine, adding an antioxidant and extracting the radiohalogenated pyrimidine from the reaction mixture. The extracted radiohalogenated pyrimidine(s) may be utilized in forming diagnostic and/or therapeutic products.
