    Applications:

     

    Catalyst:


    • Sodium tungstate is used as catalyst in paint dyes, pigment pharmaceuticals and many more chemical reactions like epoxidation of alkenes and oxidation of alcohols into aldehydes or ketones.


    Anti-Diabetic Agent:


    • Sodium tungstate is an effective antidiabetic agent when administered orally. It improves pancreatic function and beta cell proliferation. It activates glycogen synthesis through an insulin receptor-independent pathway.


    Anti-Obesity Agent:


    • There are dual effects of sodium tungstate on adipocyte biology: inhibition of adipogenesis and stimulation of cellular oxygen consumption. Sodium tungstate inhibits adipocyte differentiation and regulates the mitochondrial oxygen consumption of adipose cells. These effects contribute to the anti-obesity activity of sodium tungstate and confirm its potential as a powerful alternative for the treatment of obesity.


    Permanent Chemical Modifier:


    • Sodium tungstate is used for slurry sampling electrothermal atomic absorption spectrometric determination of indium in soils.


    Other Uses:


    • Manufacture of metal tungsten, tungsten acid, tungsten salts, dyes.
    • Manufacture of heteropolyacid color lakes used in printing inks, plants, waxes, glasses, and textiles.
    • Analytical reagent. Reagent for alkaloids, uric acid and plasma proteins.
    • Fuel-cell electrode material.
