6-chloro-1,3-dimethyl-5-nitro-pyrimidine-2,4-quinone

6-Chloro-1,3-dimethyl-5-nitrouracil is an intermediate used in the synthesis of 9-(1,3-Dioxolan-2-ylmethyl)-3,9-dihydro-1,3-dimethyl-1H-purine-2,6-dione (D486860), which is an isomer impurity in the synthesis of Doxofylline (D557100), a xanthine molecule that appears to be both bronchodilator and anti-inflammatory with an improved therapeutic window over conventional xanthines such as Theophylline and the evidence supporting the effects of Doxofylline in the treatment of lung diseases.
