The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1-Hexyl-3,7-dimethyl-1H-purine-2,6(3H,7H)-dione( cas:1028-33-7 ) is researched.Electric Literature of C13H20N4O2.Hassib, Sonia T. published the article 《Simultaneous determination of pentifylline and nicotinic acid by derivative spectrophotometry》 about this compound( cas:1028-33-7 ) in Egyptian Journal of Pharmaceutical Sciences. Keywords: pentifylline nicotinate determination derivative spectrophotometry. Let’s learn more about this compound (cas:1028-33-7).
First-derivative spectrophotometry with a zero-crossing technique of measurement was used for the quantitation of a mixture of pentifylline and nicotinic acid (4:1). Pentifylline was also evaluated in the presence of nicotinic acid by first and second-derivative modes applying peak-height measurement. Cosaldon Retard tablets were estimated for pentifylline and nicotinic acid in success using first-derivative mode.
The article 《Simultaneous determination of pentifylline and nicotinic acid by derivative spectrophotometry》 also mentions many details about this compound(1028-33-7)Electric Literature of C13H20N4O2, you can pay attention to it, because details determine success or failure
