944-73-0: 1,3-Dimethyluric Acid
1 3-dimethyluric acid or Oxytheophylline (CAS No: 944-73-0) is the major metabolite of theophylline that is used in the electrochemical and enzymic oxidation of a dialkylpurine. Theophylline is used to manage chronic asthma and for several years was approved as a first-line agent for the treatment of chronic asthma.
