Used as a reducing agent in chemical synthesis, particularly in the production of silver mirrors and in electroless plating of metals. Acts as a catalyst in the manufacturing of polylactic acid (PLA), a biodegradable polymer. Employed in textile printing and dyeing processes to fix colors on fabrics. Applied in the formulation of corrosion inhibitors and in the treatment of wastewater to reduce heavy metal ions. Also utilized in analytical chemistry for the detection and estimation of oxidizing agents like nitrite and ferric ions.
