Sodium Iodide (NaI), identified by CAS number 7681-82-5, is a chemical compound that holds significant importance across various scientific and industrial sectors. As a leading manufacturer and supplier of fine chemicals, understanding the nuanced properties and versatile uses of Sodium Iodide is key to serving our clients effectively. This article aims to provide a comprehensive overview of its characteristics and applications.

Physically, Sodium Iodide typically presents as a white, crystalline powder or colorless crystals. It is known for being hygroscopic, meaning it absorbs moisture from the atmosphere, which can lead to clumping or deliquescence if not stored properly in tightly sealed containers. Its solubility in water is quite high, facilitating its use in aqueous solutions. Boiling point is approximately 1304°C, and its melting point is around 661°C. Chemically, it acts as a source of iodide ions, which are crucial in many reactions. It can react with strong oxidizers, so care must be taken to store it separately from such substances.

The applications of Sodium Iodide are diverse. In the pharmaceutical industry, it is widely employed as a pharmaceutical intermediate in the synthesis of various drugs and therapeutic agents. Its role here is critical, demanding high purity to ensure the safety and efficacy of the final medicinal products. For procurement managers in this sector, sourcing high-purity Sodium Iodide from reliable manufacturers in China, like NINGBO INNO PHARMCHEM CO.,LTD., is a strategic necessity.

Beyond pharmaceuticals, Sodium Iodide serves as an important reagent in organic chemistry. It is used in various substitution reactions, such as the Finkelstein reaction, where it replaces other halogens on alkyl halides. This makes it invaluable for chemists engaged in complex synthesis and research. The availability of consistent quality Sodium Iodide at competitive prices is a significant factor for academic institutions and industrial research laboratories.

Furthermore, Sodium Iodide finds applications in the daily chemical industry, contributing to the formulation of certain products. Its properties also lend themselves to specialized uses, such as in certain types of X-ray contrast media or as an additive in some photographic emulsions. The compound's ability to provide iodide ions makes it a versatile component in chemical formulations.

When considering the purchase of Sodium Iodide, buyers often look for specific grades and purity levels. Understanding the specifications provided by manufacturers, such as assays and impurity profiles, is essential. For instance, a purity of ≥99% is often a standard requirement for many critical applications. Collaborating with suppliers who can provide detailed technical documentation and responsive customer support ensures that your procurement process is efficient and reliable. Whether you are looking to buy for immediate use or for long-term supply contracts, a well-established chemical supplier can meet your needs.

In essence, Sodium Iodide (CAS 7681-82-5) is a foundational chemical with indispensable roles in pharmaceuticals, research, and industry. Its chemical properties, coupled with the availability of high-purity grades from reliable sources, make it a sought-after compound for a wide array of applications. By focusing on quality and partnering with expert manufacturers, industries can effectively leverage the benefits of this versatile chemical.
