Name: 1-Hexyl-3,7-dimethyl-1H-purine-2,6(3H,7H)-dione. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-Hexyl-3,7-dimethyl-1H-purine-2,6(3H,7H)-dione, is researched, Molecular C13H20N4O2, CAS is 1028-33-7, about Determination of pentifylline in sustained release tablets. Author is Abu-Shady, Hamed A.; Hassib, Sonia T.; Youssef, Nadia F..
Pentifylline was determined by 2 sensitive methods viz: a titrimetric method in which pentifylline was treated with N-bromosuccinimide in aqueous sulfuric acid medium and a spectrophotometric method for the determination of pentifylline in the presence of nicotinic acid, recording absorbance of the mixture in methanol at 273 and 263 nm. The methods were applied with success for the evaluation of pentifylline in tablets. An attempt to determine other purine derivatives by N-bromosuccinimide is included.
