7-Methylhypoxanthine

Description

7-Methylhypoxanthine, also known as 7-methyl-7H-purin-6-ol, belongs to the class of organic compounds known as hypoxanthines. Hypoxanthines are compounds containing the purine derivative 1H-purin-6(9H)-one. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. Based on a literature review very few articles have been published on 7-Methylhypoxanthine.
