The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2-Chloropyridine 1-oxide(SMILESS: ClC1=CC=CC=[N+]1[O-],cas:2402-95-1) is researched.Quality Control of 4-Aminopyrimidine. The article 《Synthesis of 2-mercaptopyridine-1-oxide zinc salt and its crystal structure》 in relation to this compound, is published in Nanjing Gongye Daxue Xuebao, Ziran Kexueban. Let’s take a look at the latest research on this compound (cas:2402-95-1).
2-Chloropyridine-N-oxide was synthesized by treating 2-chloropyridine with hydrogen peroxide in glacial acetic acid. The final product 2-mercaptopyridine-1-oxide zinc salt was obtained from 2-chloropyridine-N-oxide via reaction with NaSH, preparation of the sodium salt and chelation with ZnSO4. The structure of the product was characterized by m.p., 1HNMR and single crystal diffractometer. The crystal belonged to monoclinic space group of P21/C with a = 0.84010(17) nm, b = 1.0184(2) nm, c = 1.3736(3) nm, α = 90.00°, β = 97.23(3)°, γ = 90.00°, Dx = 1.810 g/cm3, Z = 4, F(000) = 640, μ = 2.453 mm-1, and the final deviation factor R = (0.0325) and wR = (0.0728).
