Prototropic tautomerism of nucleic acid purine bases

Prototropic tautomerism of nucleic acid purine bases. Sheina, G. G.; Radchenko, E. D.; Stepanyan, S. G.; Blagoi, Yu. P. (Inst. Low Temp.In this article, certain chemicals are used. Some of their cas registry numbers are 109-12-6 and 22404-50-8 Phys. Eng., Kharkov, USSR). Stud. Biophys., 114(1-3), 123-31 (English) 1986. CODEN: STBIBN. ISSN: 0081-6337. DOCUMENT TYPE: Journal CA Section: 6 (General Biochemistry) The keto-enol tautomerism of purine bases was proved by low-temp. (11 K) IR spectroscopy in an Ar matrix. Spectral assignments are given for tautomeric structures of 9-methoxyguanine, hypoxanthine, adenine, isocytosine, N2-methylisocytosine, 2-aminopyrimidine, and other model purines. .

Mechanism of corrosion inhibition of copper by 2-aminopyrimidine

Mechanism of corrosion inhibition of copper by 2-aminopyrimidine. Lin, Zhonghua; Wang, Fengchun; Tian, Zhongqun (Dep. Chem., Xiamen Univ., Xiamen 361005, Peop. Rep. China). Wuli Huaxue Xuebao, 8(1), 87-93 (Chinese) 1992. CODEN: WHXUEU.Several substances with their cas registry numbers 109-12-6 and 7440-50-8 may be metioned in this study. ISSN: 1000-6818. DOCUMENT TYPE: Journal CA Section: 56 (Nonferrous Metals and Alloys) The mechanism of corrosion inhibition of Cu by 2-aminopyrimidine (I) was studied by XPS, x-ray AES, SERS, and electrochem. techniques. In acidic solns., a protective polymeric complex film consisting of I, Cl-, and surface Cu atoms or cations on the Cu surface, which is stable in a wide potential range, is responsible for the corrosion inhibition. .
