Metabolite of Theophylline and Caffeine. | [Definition]
ChEBI: An oxopurine that is xanthine in which the hydrogen attached to the nitrogen at position 7 is replaced by a methyl group. It is an intermediate metabolite in the synthesis of caffeine. | [General Description]
7-Methylxanthine is an oxopurine, which belongs to the class of xanthines. It may be synthesized by the reaction between 4-amino-1-methylimidazole-5-carboxamide and diethyl carbonate. | [Purification Methods]
Crystallise it from water. [Beilstein 26 II 263, 26 III/IV 2330.] |
