Sodium Iodide (NaI) stands as a crucial inorganic compound, widely valued as an excellent source of iodide ions for a multitude of applications. Presented as a colorless or white cubic crystal, it is an odorless substance characterized by a distinct bitter salty taste. This crystalline form is a versatile raw material, essential for processes in various industries.

The physical and chemical profile of Sodium Iodide contributes significantly to its utility. It boasts a molecular weight of 149.89400 and a density of 3.66. Key thermal properties include a melting point of 661 °C and a boiling point of 1300 °C. One of its most notable features is its exceptional solubility. Sodium Iodide is easily soluble in water, with a high solubility of 184 grams per 100 mL at 25 ºC. It also shows good solubility in organic solvents such as ethanol, acetone, methanol, and glycerin, while being only slightly soluble in ether. Dissolution in water is an endothermic process (heat absorption). The compound is generally considered stable under normal temperatures and pressures and should be stored at room temperature.

The application spectrum of Sodium Iodide is remarkably broad. In the pharmaceutical sector, it is a fundamental raw material for the preparation of various iodide compounds. Medicinally, it has been used as a goiter control agent, an absorbent for vitreous turbidity in the eyes, and as an expectorant and diuretic. Beyond pharmaceuticals, Sodium Iodide is critical in the photographic industry, serving as a photosensitive emulsifier and a mordant for color photography. Its uses extend to the food industry as an additive, and it functions as a fluxing agent and in lithographic printing. Furthermore, high-purity Sodium Iodide is indispensable as an analytical reagent, frequently employed in chromatographic analysis and spot analysis.

Maintaining high quality is paramount for Sodium Iodide, particularly for its sensitive applications. Analysis standards confirm the product's integrity. Appearance should be a White crystalline powder. A key quality metric is the Assay, demonstrating the purity level. High-quality Sodium Iodide is specified to have an Assay of ≥99.0%. Rigorous control is exercised over impurities, with typical limits set for Heavy metals (≤10ppm), Chloride (Cl⁻ ≤0.5%), Sulfate (SO₄²⁻ ≤0.04%), and Water (≤0.5%). These standards ensure the reliability and performance of the product in demanding applications.
