New Synthetic Pathways for Thiocarbohydrazide and Salicylaldehyde Azine Compounds

Spectroscopic characterization, molecular docking and machine learning studies of sulphur containing hydrazide derivatives

“…The crude product was purified by dissolving it in water at 40 °C and cooling to room temperature first before refrigeration at 0 °C for 12 hours (reported in the literature). 46 White needle like crystals thus obtained were washed with methanol and dried in a vacuum. The yield was 90%.…”

Synthesis of new metal‐free 1,2,4,5,9,10,12,13‐octaaza[16]annulene derivatives using the reaction of vinamidinium salts with thiocarbohydrazide

“…[ 33–36 ] Thiocarbohydrazide was synthesized according to literature procedures. [ 37,38 ] 1H and 13C‐NMR spectra were recorded with a Bruker Avance DRX‐300. d6‐DMSO was used as solvent and TMS as internal standard.…”

Aminophosphonate CuO nanocomposites for uranium(VI) removal: Sorption performance and mechanistic study

“…The aromatic ring of p-phthalaldehyde is identified at 2935-2915 cm − 1 (stretching vibration) [23] and 1490-1410 cm − 1 (aromatic C-H bending and/or aromatic C=C stretching) [23]. The main bands assigned to N-based compounds (amine groups, both primary and secondary) are identified within the range 3460-3200 cm − 1 (stretching) [59,60]; 1610-1600 cm − 1 (bending) [19]. The presence of S-based moiety (i.e., C=S) is authenticated by the band observed at 1335-1325 cm − 1 [61].…”
