Potassium Iodide (KI), identified by its CAS number 7681-11-0, is a compound whose scientific significance is as vast as its practical applications. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-grade KI, enabling its use in sophisticated scientific endeavors ranging from chemical synthesis to advanced analytical techniques.

As a chemical compound, Potassium Iodide is an ionic salt formed from potassium and iodine. It typically appears as a white crystalline powder, characterized by its solubility in water and ethanol. The chemical properties of potassium iodide are central to its utility. The iodide ion (I-) is a mild reducing agent, easily oxidized to elemental iodine (I2) by stronger oxidizing agents, a reaction fundamental to many analytical procedures, such as iodometric titrations.

In organic synthesis, KI is a critical source of iodide ions. It plays a pivotal role in reactions like the Sandmeyer reaction, used for preparing aryl iodides from diazonium salts. Aryl iodides are highly valuable intermediates for introducing aryl groups into organic molecules via nucleophilic substitution. The efficiency and purity of the KI used directly impact the success of these synthetic pathways. Therefore, sourcing high-quality potassium iodide powder is paramount for chemists engaged in complex molecular construction.

Beyond synthesis, KI serves as a key reagent in analytical chemistry. Its reaction with free iodine to form triiodide (I3-) is the basis for quantifying oxidizing agents in various industrial and environmental analyses. Furthermore, its use in starch-iodine testing, where it acts as an iodine source to form a characteristic blue-black complex with starch, is a classic method for detecting trace amounts of oxidizing agents. These applications highlight the importance of understanding the potassium iodide CAS 7681-11-0 for accurate scientific measurements.

The compound's physical characteristics also contribute to its widespread adoption. Its stability and manageable reactivity make it a preferred choice in research laboratories.
