Abstract
Electrospray ionization mass spectrometry is used to study thymidine solutions in the presence of copper ions and EDTA. The results show the existence of thymidine-EDTA complexes in the absence of CuCl2 in solution and the existence of thymidine-EDTA-CuCl2 complexes in a CuCl2 and EDTA containing thymidine solution. The stoichiometry of the complexes is determined.
