Synthesis of 14C-labeled 4-ethoxy-2, 3-benzodioxin-1-ol (EtO-BD) from [1 (4, 5, 8) -14C] naphthalene and the decomposition behavior of the labeledEtO-BD are described. 14C-EtO-BD is stable over months as long as kept at . -40°C as a solid state, and over weeks in acetonitrile. The decomposition ofEtO-BD is facilitated by the presence of H2O giving rise to two major decomposition products, o-phthalaldehydie acid and its ethyl ester. Thus the generation ofOHradical is expected on its decomposition path and is enhanced as increasingH2O concentration.Fe (II) seems to facilitateEtO-BD decomposition through the electron transfer reaction.
