Pyrimidine is a nitrogenous base similar to benzene (a six-membered ring) and includes cytosine, thymine, and uracil as bases used for DNA or RNA. 109-12-6, formula is C4H5N3, Name is Pyrimidin-2-amine. Pyrimidine also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. Application In Synthesis of 109-12-6.
Guan, Shengjie;Wu, Fan;Wu, Qian;He, Zhichao;Jiang, Jing;Huang, Yudong;Liu, Li research published 《 Modification of silicone resins by Si-N cross-dehydrocoupling with perfect thermal stability and mechanical performance》, the research content is summarized as follows. A series of new types of modified hydrosilanes were synthesized, using hydrosilanes and nitrogen heterocycles (triethoxysilane, 2-aminopyrimidine, 1,2,4-triazin-3-amine, benzylamine and 2-aminobenzothiazole), by Si-N cross-dehydrocoupling catalyzed by Ru3CO12. The results of the synthesis were then demonstrated by 1H NMR and GPC testing. Furthermore, modified silicone resins were obtained by a hydrolytic condensation reaction catalyzed by tetramethylammonium hydroxide and characterized by TGA, DSC and FT-IR. Next, excellent thermal stabilities were determined (best initial decomposition temperature was approx. 400°C, T95% was 595°C, the mass residue rate at 800°C was 87.2%). Carbon fiber reinforced silicone matrix composites were manufactured according to the tech. process developed using DSC and rotary viscometer test results, and the mech. property (ILSS) showed great improvement from 34.8 to 45.8 MPa because of the modification of Si-N cross-dehydrocoupling. After pyrolysis up to 1000°C, the composites still showed a superior ILSS value (19.6 MPa) and the modified silicone resins had a more regular and rounded microstructure and appeared to have ceramic-like particles of Si3N4. This work indicated that the silicone resin (Si-N) modified by cross-dehydrocoupling had greater competitiveness in the field of resin matrix composites.
Application In Synthesis of 109-12-6, 2-Aminopyrimidine is a useful research compound. Its molecular formula is C4H5N3 and its molecular weight is 95.1 g/mol. The purity is usually 95%.
2-Aminopyrimidine is an organic compound that belongs to the group of pyridines.
