Abstract

(2,4,6‐^14^C)‐Cyanuric acid was prepared from ^14^C‐urea by the heterocyclization of the latter in the presence of ammonium chloride. This procedure involves solvent‐free fusing of the reactants in a vacuum sealed glass tube. The product was purified by ion‐exchange column chromatography using Sephadex SE C‐25. A radiochemical yield of 60.5% was obtained based on ^14^C‐urea and the product had a specific activity of 19.06 mCi/mmol. Copyright © 2002 John Wiley & Sons, Ltd.
