Used primarily as a strong base anion exchange resin in its hydroxide form, this chemical is widely applied in water purification systems to remove anionic contaminants such as nitrates, sulfates, and heavy metal complexes. It is effective in demineralization processes where both cationic and anionic impurities must be eliminated. Commonly employed in industrial wastewater treatment, it helps in the recovery and separation of valuable chemicals, including organic acids and pharmaceutical intermediates.

In the food and beverage industry, it is utilized for deacidification and purification of sugar syrups and fruit juices by removing undesirable anions and color bodies. It also plays a role in the production of clean solvents and in catalyzing base-driven organic reactions due to its high functional group density and stability. Its macroreticular structure provides good mechanical strength and resistance to fouling, making it suitable for continuous processes in fixed-bed reactors. Regeneration with sodium hydroxide allows for repeated use, enhancing cost efficiency in large-scale operations.
