Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Soil Science Society of America Journal called Nonhydrolyzable organic nitrogen in soil size separates from long-term agricultural experiments, Author is Leinweber, P.; Schulten, H.-R., which mentions a compound: 616-43-3, SMILESS is CC1=CNC=C1, Molecular C5H7N, Synthetic Route of C5H7N.
Total N (Nt), hydrolyzed N, NH3-N, and nonhydrolyzed N were determined in soil particle-size separates from unfertilized or manured treatments in five long-term (15-108 yr) experiments in Germany. The concentrations of all N fractions (i) increased with decreases in particle size and (ii) were higher in samples from manured treatments. Irresp. of particle size and soil management, nonhydrolyzed N accounted for 7 to 31% of Nt (mean: 19%). On average, 53% of nonhydrolyzed N could be volatilized by pyrolysis. Field-ionization mass spectra of the pyrolyzates of two hydrolysis residues showed that N heterocycles are major constituents of nonhydrolyzed N. In addition, 28 to 34% of total ionintensity was assigned to low-mass N compounds and aliphatic nitriles and amides. Shifts to higher volatilization temperatures with maxima at 450 to 520° in the thermograms of all N compounds indicated that chems. stability, or strong bonds to soil minerals, are main reasons for the resistance of these mols. to acid hydrolysis. Curie-point pyrolysis-gas chromatog./mass spectrometry using a N-selective detector and library searches enabled the identification of aliphatic, carbocyclic, and aromatic amines and nitriles, benzothiazole, substituted imidazoles, substituted pyrroles and pyrrolidine, substituted pyrazoles, and isoquinoline derivative, substituted pyrazines and piperazine, pyridine, and methylpyridine. In addition, low-mass N compounds such as hydrocyanic acid, N2, nitrogen monoxide, isocyanomethane, and hydrazoic acid were assigned so that, in total, 37 compounds were identified in the pyrolyzates of nonhydrolyzed N. Within this fraction, the authors distinguished (i) proteinaceous materials, nonhydrolyzable probably due to binding or occlusion by pedogenic oxides, and (ii) highly alkyl-substituted N heterocycles, which are structural constituents of stable humic substances.
After consulting a lot of data, we found that this compound(616-43-3)Synthetic Route of C5H7N can be used in many types of reactions. And in most cases, this compound has more advantages.
