  • Applications

    Sodium chloride (CAS 7647-14-5) is a widely used salt with fundamental applications across industries. In food processing, it enhances flavor, acts as a preservative, and supports curing and brining; in chemical manufacturing, it serves as a feedstock for electrolysis to produce chlorine and sodium hydroxide (NaOH). In water treatment, it is used for regenerating ion-exchange resins and for water softening. In agriculture, it is used as a salt supplement for livestock and poultry. In pharmaceutical contexts, it serves as a formulation component and as isotonic saline solutions in medical preparations. In winter road maintenance, it is used for de-icing and preventing ice formation on roads.
