CAS 7681-11-0: Kaliumiodid
Beschreibung:
Kaliumiodid (KI) ist eine anorganische Verbindung, die durch ihr weißes, kristallines Aussehen und ihre hohe Löslichkeit in Wasser gekennzeichnet ist. Sie besteht aus Kaliumionen (K) und Iodidionen (I) und bildet eine stabile ionische Verbindung. KI wird häufig in verschiedenen Anwendungen eingesetzt, unter anderem als Nahrungsergänzungsmittel zur Vorbeugung von Jodmangel, in medizinischen Behandlungen wie dem Schutz der Schilddrüse während der Strahlenexposition und in Laborumgebungen als Reagenz. Die Verbindung zeigt Eigenschaften wie Hygroskopizität, was bedeutet, dass sie Feuchtigkeit aus der Luft aufnehmen kann, und sie kann auch mit starken Oxidationsmitteln reagieren. In Lösung kann Kaliumiodid Iodidionen freisetzen, die für die Synthese von Schilddrüsenhormonen unerlässlich sind. Darüber hinaus ist KI bekannt für seine Rolle bei der Bildung von Iod-Stärke-Komplexen, die in Titrationen und der analytischen Chemie verwendet werden. Sicherheitsüberlegungen umfassen den vorsichtigen Umgang, da übermäßige Exposition zu Reizungen oder anderen Gesundheitsproblemen führen kann. Insgesamt ist Kaliumiodid eine vielseitige Verbindung von erheblicher Bedeutung sowohl für die Gesundheit als auch für die wissenschaftliche Forschung.

Potassium iodide, 99.9% (metals basis)
CAS:Potassium iodide is both a source of iodide and a mild reducing agent. It is used as a component in the electrolyte of dye sensitized solar cells. In the field of synthetic organic chemistry, it is used in the preparation of alkyl or aryl iodo compounds. It is employed as a nucleophilic catalyst in the alkylations with alkyl bromide, chloride, tosylate and mesylate. In the presence of acid it forms hydroiodic acid, which is a strong reducing agent. It is useful in producing Lugol’s solution (or Lugol’s iodne) which finds many applications including starch testing, gram stains, and etching of gold surfaces.

CAS:Potassium iodide is used in pharmaceutical formulations and in film photography as a source of iodine. It is widely used as an analytical Reagent in iodometric tritrations. Apart from its application as a source of iodide to produce organo iodine compounds such as in Sandmeyer reactions, potassium iodide finds extensive use as a nucleophilic catalyst for several alkylation reactions.

CAS:Potassium iodide is a chemical compound that is used as a nutrient solution in the production of polyvinyl chloride. It reacts with sodium trifluoroacetate to produce potassium trifluoroacetate, which is then reacted with copper chloride to form copper trifluoride. The reaction produces hydrogen fluoride gas and anhydrous sodium carbonate. Potassium iodide has been shown to have some antiviral effects against hepatitis B virus and the herpes simplex virus type 1. This compound can also be used in wastewater treatment processes because it reacts with trifluoroacetic acid to form carbon dioxide and sodium bicarbonate. Potassium iodide can be titrated with hydrochloric acid or acetic acid to determine its concentration. In addition, potassium iodide can be used for chemiluminescent reactions and electrochemical impedance spectroscopy experiments.Formel:IKReinheit:Min 99%Farbe und Form:White Off-White PowderMolekulargewicht:166 g/molPotassium iodide, 99+% (ACS)
