Key Physico-Chemical Properties

Our Sodium Iodide exhibits distinct physical characteristics that ensure consistent performance in diverse applications. The compound appears as a colorless or white cubic crystal with an odorless profile and a strong bitter salty taste. It demonstrates high solubility in water, ethanol, acetone, methanol, and glycerin, while remaining slightly soluble in ether. The high density of 3.66 g/cm³ and specific melting point of 661°C contribute to its reliability in high-temperature processes. Users should note that the dissolution process is endothermic, absorbing heat when mixed with solvents. The refractive index of 1.7745 further confirms its optical purity suitable for specialized analytical tasks. These properties make it a versatile component in complex chemical formulations requiring precise ionic strength.

Industrial and Commercial Applications

The versatility of Sodium Iodide makes it a preferred choice for multiple industries. In organic chemistry, it serves as a fundamental source of iodide ions for nucleophilic substitution reactions, such as the Finkelstein reaction, facilitating the conversion of alkyl chlorides or bromides to alkyl iodides. The photographic industry utilizes this compound as a photosensitive emulsifier and color photo mordant, enhancing image quality and sensitivity. In the pharmaceutical sector, it acts as a raw material for preparing iodides and serves specific therapeutic roles under regulated conditions, including use as an expectorant. Additionally, it is employed as a food additive for iodization to prevent deficiencies, a fluxing agent in metallurgy, and a critical analytical reagent for chromatographic and spot analysis in quality control laboratories. Its role in dye preparation further expands its utility in the textile and chemical manufacturing sectors.

Quality Assurance and Specifications

We prioritize quality control to ensure every batch conforms to factory standards and client requirements. Our manufacturing process guarantees high assay levels with minimal impurities. Heavy metals are strictly controlled to ensure safety in sensitive applications. Each shipment is accompanied by a Certificate of Analysis (COA) verifying parameters such as assay, chloride content, sulfate content, and water loss. Our internal testing confirms an assay of ≥99.0%, with heavy metals below 10ppm, ensuring compliance with rigorous industrial norms. We maintain detailed records for every production run to ensure full traceability and accountability.

Handling and Storage Guidelines

To maintain optimal quality, Sodium Iodide should be stored at room temperature in a dry, well-ventilated area. The compound is stable under normal temperatures and pressures but should be protected from moisture to prevent caking. Personnel handling this material should follow standard safety protocols, including the use of protective equipment. Proper storage conditions ensure the product remains free-flowing and retains its chemical integrity throughout its shelf life. We recommend regular inventory checks to manage stock rotation effectively. Packaging is designed to protect against environmental factors during transit, ensuring the material arrives in pristine condition for immediate use in your facilities.
