Tetrazoles and their derivatives are insensitive energetic molecules that can be used in the compounding of the high energy material. Herein, two types of bis hyroxyethyl tetrazole compounds have been synthesized using bisnitrile and sodium azide and via consequent alkylation of the reaction product .The structure of all products have been confirmed by 1HNMR, MASS spectroscopy and elemental...

Complexes [CrO2 (C8H5O4) (H2O) 3] and [CrO2 (C8H5O4) (H2O) 3] .H2O were prepared by reduction of CrO3 at room temperature by ethanol in the presence of phthalic acid (H2pht) yield solution that contains monomeric and dimeric Cr (III) complexes. A solution H2pht/Cr molar ratio of 1:1 and 1:2 is indefinitely stable towards precipitation. Their analysis were done by using elemental (C and H), ICP-...

Lignin peroxidase shares several structural features with the well-studied horseradish peroxidase and cytochrome c peroxidase but carries a higher redox potential. Here the heme domain of lignin peroxidase and the lignin peroxidase cyanide adduct was examined by 1HNMR spectroscopy, including nuclear Overhauser effect and two-dimensional measurements, and the findings were compared with those fo...

BACKGROUND Acute pancreatitis (AP) is a common inflammatory disease of the pancreas accompanied by serious metabolic disturbances. Nevertheless, the specific metabolic process of this disease is still unclear. Characterization of the metabolome may help identify biomarkers for AP. To identify potential biomarkers, this study therefore investigated the 1H-nuclear magnetic resonance (NMR)-based m...
