The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5-(4-Pyridyl)-1H-tetrazole( cas:14389-12-9 ) is researched.Application of 14389-12-9.Yang, Gao Wen; Zhang, Yuan Ting; Wu, Qi; Cao, Meng Jie; Wu, Jiao; Yue, Qiu Yan; Li, Qiao Yun published the article 《Nitrogen-rich 5-(4-pyridyl)tetrazole-2-acetic acid and its alkaline earth metal coordination polymers for potential energetic materials》 about this compound( cas:14389-12-9 ) in Inorganica Chimica Acta. Keywords: magnesium calcium strontium barium pyridyltetrazoleacetate polymer preparation thermal explosion; crystal structure magnesium calcium strontium barium pyridyltetrazoleacetate polymer. Let’s learn more about this compound (cas:14389-12-9).
Tetrazole and its derivatives with rich nitrogen atoms may be potential candidates for energetic materials. Alk. earth metal coordination compounds based on such ligands are relatively less investigated. Hpytza was prepared from 4-cyanopyridine and sodium azide, Et bromoacetate, where Hpytza = 5-(4-pyridyl)tetrazole-2-acetic acid. Hpytza and four alk. earth metal coordination polymers [Mg(pytza)2]n (1), [Ca(pytza)2(H2O)2]n·3nH2O (2), [Sr(pytza)2(H2O)2]n (3) and [Ba(pytza)2(H2O)2]n·nH2O (4) were prepared under solvothermal conditions. The thermal behavior of these compounds were characterized by the differential scanning calorimetry (DSC) and thermogravimetric-differential thermogravimetric (TG-DTG) analyses. Furthermore, the critical temperature of thermal explosion and relevant thermal parameters ΔS, ΔH, ΔG of Hpytza and polymers 1-4 were calculated, as well, indicating that these compounds are potential energetic materials.
This literature about this compound(14389-12-9)Application of 14389-12-9has given us a lot of inspiration, and I hope that the research on this compound(5-(4-Pyridyl)-1H-tetrazole) can be further advanced. Maybe we can get more compounds in a similar way.
