Used as a reducing agent in chemical synthesis, particularly in the production of pharmaceuticals and organic compounds. It helps in the removal of oxygen from reaction mixtures, preventing oxidation of sensitive materials. Commonly applied in water treatment as an oxygen scavenger to protect metal surfaces from corrosion in boiler systems. Also utilized in the textile industry for dyeing and printing processes, where it stabilizes colorants and improves color fastness. Its ability to donate electrons makes it useful in electroless plating processes for metal coating.
