Industrial Uses

1. Pharmaceuticals

  • Radioactive protection: Potassium iodide is used to protect the thyroid gland from taking in radioactive iodine that may be released during a nuclear radiation emergency.
  • Expectorant: Reduces viscosity of mucus by increasing respiratory tract secretions.

2. Food & Healthcare Ingredients

  • Iodine Supplementation: KI is added to salt, making it a convenient and affordable way for people to get the iodine they need.
  • Stability and Taste: KI is highly stable and doesn't alter the taste, color, or texture of salt, making it a suitable choice for fortification.

3. Performance Chemicals

  • Iodide Source: KI is a convenient and readily available source of iodide ions, making it suitable for nucleophilic displacement reactions in various organic synthesis processes.
  • Synthesis of Specific Compounds: KI is used in the synthesis of various compounds, including silver iodide (AgI) for photographic film, as well as in reactions involving oxidation, halide exchange, and redox processes.
  • Sandmeyer Reaction: In the Sandmeyer reaction, KI is crucial for converting aryl diazonium salts (formed from aryl amines) into aryl iodides. The iodide ion (I-) acts as a nucleophile, displacing the diazo group (N2+) to form the aryl iodide.

4. Animal Healthcare

  • Antifungal treatment: Potassium iodide has been used to treat fungal granulomatous disease and infections associated with zygomycetes. In small animals, it has been used for sporotrichosis.
