In this paper, we report the crystal structure of 2-[2-(diphenylphosphoryl)phenyl]-1H-perimidine (L1) obtained from ring closure reaction 1,8-diaminonaphthalene and 2-(diphenylphosphino)benzaldehyde, followed by dehydrogenation with sodium metabisulfite (Na2S2O5). L1 was characterised using 1H, 13C & 31P NMR, FT-IR X-ray single analyses.

Sulfurous compounds: sodium sulfite Na2SO3 (E 221), sodium bisulfite NaHSO, (E 222), and sodium metabisulfite Na2S2O5 (E 223) are largely used as antioxidants in many pharmaceutical formulations. A method for determination of sodium metabisulfite in parenteral formulations containing tartrate ions was developed. High-performance ion chromatography (HPIC) method with suppressed conductivity dete...

The effect of salbutamol on bronchoconstriction induced by inhaled sodium metabisulphite has been studied in 12 atopic subjects. Salbutamol (200 micrograms, 3.5 x 10(-7) M) and matched placebo were administered by identical metered dose inhaler 15 min before a dose-response to sodium metabisulphite (1.25-100 mg ml-1) was performed. Geometric mean provocative dose of metabisulphite causing a 35%...

This study investigates the impacts of chemical preservation on the performance of polyamide reverse osmosis membranes with respect to water permeability and solute rejection. Three preservative chemicals, namely formaldehyde, sodium metabisulfite, and 2,2-Dibromo-3-Nitrilopropionamide, were evaluated for membrane preservation at pH 3 and 7. Experimental data show that chemical preservation may...

BACKGROUND The authors previously showed that propofol attenuates bronchoconstriction. Recently, a newer formulation of propofol with metabisulfite preservative has been introduced. metabisulfite causes airway narrowing in asthmatics. Therefore, we tested whether the preservative metabisulfite abolishes the ability of propofol to attenuate bronchoconstriction. The authors used a sheep model in ...

Cucumber (Cucumis sativus L.) is a commercially cultivated worldwide as a seasonal vegetable crop. The aim of the experiment was to compare the effect of different chemical additives namely Sodium benzoate, Potassium metabisulfite( KMS) and their combination, on the physicochemical and phytochemical parameters and antioxidant activity of cucumber juice. The storage was done for 6 months at room...
