Effect of solvents on the fluorescence characteristics of 6-anilinopurine and 6-piperidinopurine was written by Abdullah, Zanariah;Bakar, Maizathul Akmam A.;Mohd Shariffuddin, Mohd Adlan;Aiyub, Zaharah. And the article was included in Journal of Ultra Chemistry in 2006.Application of 1928-81-0 This article mentions the following:
6-Chloropurine which was obtained com. was used as the precursor for the preparation of 6-anilinopurine and of 6-piperidinopurine. Fluorescence studies were carried out in 75% ethanol, acetonitrile and Et acetate. Both compounds showed the highest fluorescence peak in Et acetate whereby 6-piperidinopurine showed fluorescence peak at 373 nm, when excited at 315 nm, and 6-anilinopurine showed fluorescence peak at 447 nm when excited at 321 nm. The fluorescence intensity of 6-anilinopurine and 6-piperidinopurine decreased with time. In the experiment, the researchers used many compounds, for example, 6-(Piperidin-1-yl)-9H-purine (cas: 1928-81-0Application of 1928-81-0).
6-(Piperidin-1-yl)-9H-purine (cas: 1928-81-0) belongs to piperidine derivatives. Piperidine is a metabolite of cadaverine, a polyamine found in the human intestine. Piperidine prefers a chair conformation, similar to cyclohexane. Unlike cyclohexane, piperidine has two distinguishable chair conformations: one with the N–H bond in an axial position, and the other in an equatorial position.Application of 1928-81-0
