Safety of 1H-1,2,4-Triazol-5-amine. Recently I am researching about INTRAMOLECULAR HYDROGEN-BOND; CRYSTAL-STRUCTURE; SOLID-STATE; SPECTROSCOPIC CHARACTERIZATION; DERIVATIVES; N-15; IR; H-1-NMR; 2-HYDROXY-1-NAPHTHALDEHYDE; UV/VIS, Saw an article supported by the National Science CentreNational Science Centre, Poland [2017/01/X/ST4/01132]. Published in ELSEVIER SCIENCE BV in AMSTERDAM ,Authors: Kolodziej, B; Morawiak, M; Schilf, W; Kamienski, B. The CAS is 61-82-5. Through research, I have a further understanding and discovery of 1H-1,2,4-Triazol-5-amine
In the present paper, twelve Schiff bases derived from 3-amino-1H-1,2,4-triazole (ATz) and various benzaldehydes, and salicylaldehydes were synthesized. The H-1, C-13, and N-15 NMR data are discussed in relation to the structure of ATz and its imine products. In addition, X-ray, ATR-FTIR, and UV-Vis analytical techniques are used for structure elucidation of ATz-based Schiff bases. It was found that the starting material, 3-amino-1H-1,2,4-triazole, exists as tautomeric mixture of three forms (Graphical Abstract) in solution, whereas in the solid state (C-13 and N-15 CPMAS data) potentially tautomeric proton is located on nitrogen atom traditionally marked as N-2 (Graphical Abstract, 2N-H structure). All investigated Schiff bases derived from salicylaldehydes exist in both phases as tautomeric equilibrium mixtures, where enol-imine forms are dominated structures. The positions of those equilibria only very slightly depend on substituents in phenol ring. Generally, the contributions of keto-amine forms in the solid state are higher comparing with DMSO solutions. (C) 2019 Published by Elsevier B.V.
