Description

Potassium triiodide (K₃I₃) is an inorganic compound composed of potassium iodide and iodine in a molecular ratio of 3:1. It appears as a yellow-brown solid or crystalline substance and is highly soluble in water. When dissolved in water, it forms a deep brown solution due to the presence of iodine molecules in the solution. Potassium triiodide is relatively unstable and can decompose into potassium iodide and iodine, especially under heat or light, which results in the release of iodine gas.

ChEBI: Iodine aqueous is an organic molecular entity.

Lugol solution is comprised of aqueous potassium iodide plus iodine.

Experimental reproductive effects. When heated to decomposition it emits toxic fumes of I-.

Drug Information

MeSH：

Drugs that act locally on cutaneous or mucosal surfaces to produce inflammation; those that cause redness due to hyperemia are rubefacients; those that raise blisters are vesicants and those that penetrate sebaceous glands and cause abscesses are pustulants; tear gases and mustard gases are also irritants. (See all compounds classified as Irritants.)|Chemicals and substances that impart color including soluble dyes and insoluble pigments. They are used in INKS; PAINTS; and as INDICATORS AND REAGENTS. (See all compounds classified as Coloring Agents.)|Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure. (See all compounds classified as Hemostatics.)

GRAM'S IODINE Use and Manufacturing

Uses

Potassium triiodide is primarily employed as a reagent in chemical analysis, particularly for titrations, where it is used to determine the concentration of substances in solution, such as reducing agents or certain metals. It also finds application in the synthesis of other iodine-containing compounds. In addition, it is sometimes used in the formulation of iodine-based disinfectants and in the pharmaceutical industry for specific preparations.

Lugol solution has been used in a study to assess narrow-band imaging without image magnification for detecting high-grade dysplasia and intramucosal esophageal squamous cell carcinoma. It has also been used in a study to determine its benefit in aiding detection of the presence and spread of small squamous cell carcinomas of the esophagus.
