1. Pharmaceuticals

• Antiseptic and supplement ingredient: Iodine prills are a key source of iodine used in the production of povidone-iodine, an antiseptic applied to wounds and surgical areas. Iodine is also essential for thyroid health, so it’s used in nutritional supplements (e.g., potassium iodide tablets). The prill form ensures high purity, easy dosing, and safer storage.

2. Food & Healthcare Ingredients

• Fortification of salt and dietary supplements: Iodine prills are used to manufacture iodized salt—a key public health intervention to prevent iodine deficiency disorders such as goiter and mental impairment. They are also used in nutraceuticals and functional foods for health and wellness.

3. Animal Healthcare

• Micronutrient additive: Livestock and poultry require iodine for proper metabolism and growth. Iodine prills are processed into compounds like calcium iodate and ethylenediamine dihydroiodide, which are added to animal feed to maintain thyroid health and reproductive efficiency.

4. Water Treatment

• Biocide and disinfectant component: Iodine prills are used to make water purification tablets for drinking water, especially in field conditions or emergency kits. They release iodine slowly, effectively killing bacteria, viruses, and protozoa. Iodine is also used in sanitation systems for industrial and municipal water.

5. Performance Chemicals

• Reagent for redox titrations: In labs, Iodine prills are used for iodometric titrations to determine concentrations of reducing agents like sulfites or vitamin C. Their stable, solid form allows accurate measurement and reduced loss by sublimation.
• Intermediate in synthesis of iodine compounds: Iodine prills are used to produce inorganic and organic iodine derivatives, such as potassium iodide, iodoform, and various iodinated hydrocarbons. These compounds are used in dyes, catalysts, disinfectants, and pharmaceuticals.

6. Fabric Solutions 

• Disinfectant in industrial laundering: Iodine prills are used in formulations for disinfecting hospital linens, uniforms, and food-grade textiles. Their use helps prevent microbial contamination in large-scale laundering and fabric treatment operations.
