Synthesis, And Studying Effect Of A Solvent On The 1h-Nmr Chemical Shifts Of 4-Azido-N-(6-Chloro-3-Pyridazinyl) Benzenesulfonamide, Sadiq M. Hasan
Synthesis, And Studying Effect Of A Solvent On The 1h-Nmr Chemical Shifts Of 4-Azido-N-(6-Chloro-3-Pyridazinyl) Benzenesulfonamide, Sadiq M. Hasan
Al-Qadisiyah Journal of Pure Science
The compound 4-Azido-N-(6-chloro-3-pyridazinyl)benzenesulfonamide was synthesized and studied using FTIR, and 1H-NMR . The influence of a solvent on the experimental 1H-NMR chemical shifts of title compound is discussed. Small chemical shift Δδ < 0.1 ppm were observed when switching from DMSO-d6 to CD3OD. Record a marked change in chemical shifts valeues Δδ > 0.3 ppm when transform from high-polar solvents (DMSO-d6,and CD3OD) to low-polar solvent (CDCl3). The 1H-NMR chemical shifts of C2-H and C6-H were shown to have excellent linear correlation with the dielectric constants of the solvents DMSO-d6, CD3OD,and CDCl3 (r = 0.995). The 1H-NMR chemical shifts of C18-H shows a perfect relationship with solvatochromic parameter β (r = 0.999).

Organotin (IV) complex is part of the organometallic chemistry and in recently decades have a variety of interesting and application used it. A new class of metallomesogens LC (A) Ph3Sn(VAL), (B) Bu3Sn(VAL), (C) Ph2Sn(VAL)2 and (D) Bu2Sn(VAL)2 was synthesis through the reaction of valsartan ligand with (di- or tri- butyl tin chloride salt) and (di- or tri- phenyl tin chloride salt) in methanol solvent. 1H NMR,119 Sn NMR, FTIR and CHN elemental analyses were measure and the liquid crystalline properties were study by POM. The mesophase in all organotin (IV) carboxylate complexes are thermotropic nematic phase. In complexes (A, C) …

Al-Qadisiyah Journal of Pure Science
A new dye AZO 4-antipyl azo (benzoic acid) was prepared. The possibility of adsorption of the water solution to the dye was studied on a raw white cloth surface where the cloth was treated and the impurities removed Before conducting adsorption experiments. The results showed that the suitable conditions for the adsorption process were in the acidic medium of the water solution of the dye. In the neutral and basal medium, the adsorption process was not induced. The effect of temperature on the adsorption process was also studied , The aim of this study was to use dye prepared in …

The menopause correlate with changes in physiological, psychological and biochemical characterized, and also body mass index. The study was analyzed the level of glutamic pyruvic transaminase activity (GPT) , glutamic oxaloacetic transaminase activity (GOT) , alkaline phosphatase activity (ALP) and estimation of body mass index (BMI) in postmenopausal women (n=20) (50-70)years old and premenopausal women (n=20) (30-40) years old. In postmenopausal women the activity of glutamic pyruvic transaminase (GPT) , glutamic oxaloacetic transaminase activity (GOT) , alkaline phosphatase activity (ALP) and body mass index (BMI) was elevated significantly as compared to premenopausal women (p<0.05) , (P<0.004) , (P<0.002) and (p<0.016) respectably . This study showed with age advances liver become injury and gets abnormal liver functions.
