CAS 7681-11-0: Iodure de potassium
Description :
Iodure de potassium (KI) est un composé inorganique caractérisé par son apparence blanche et cristalline et sa haute solubilité dans l'eau. Il est composé d'ions potassium (K) et iodure (I), formant un composé ionique stable. KI est couramment utilisé dans diverses applications, y compris comme complément alimentaire pour prévenir la carence en iode, dans des traitements médicaux tels que la protection de la thyroïde lors de l'exposition aux radiations, et dans des environnements de laboratoire comme réactif. Le composé présente des propriétés telles que l'hygroscopicité, ce qui signifie qu'il peut absorber l'humidité de l'air, et il peut également réagir avec des agents oxydants forts. En solution, Iodure de potassium peut libérer des ions iodure, essentiels à la synthèse des hormones thyroïdiennes. De plus, KI est connu pour son rôle dans la formation de complexes iodure-amidon, utilisés dans les titrations et la chimie analytique. Les considérations de sécurité incluent de le manipuler avec soin, car une exposition excessive peut entraîner des irritations ou d'autres problèmes de santé. Dans l'ensemble, Iodure de potassium est un composé polyvalent d'une importance significative tant pour la santé que pour la recherche scientifique.

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 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.Formule :IKDegré de pureté :Min 99%Couleur et forme :White Off-White PowderMasse moléculaire :166 g/molPotassium iodide, 99+% (ACS)
