CAS 7681-11-0: Iodeto de potássio
Descrição:
Iodeto de potássio (KI) é um composto inorgânico caracterizado por sua aparência branca e cristalina e alta solubilidade em água. É composto por íons de potássio (K) e iodeto (I), formando um composto iônico estável. KI é comumente usado em várias aplicações, incluindo como suplemento dietético para prevenir a deficiência de iodo, em tratamentos médicos como proteção da tireoide durante a exposição à radiação, e em ambientes de laboratório como reagente. O composto exibe propriedades como higroscopicidade, o que significa que pode absorver umidade do ar, e também pode reagir com agentes oxidantes fortes. Em solução, Iodeto de potássio pode liberar íons de iodeto, que são essenciais para a síntese de hormônios tireoidianos. Além disso, KI é conhecido por seu papel na formação de complexos de iodo-amido, que são usados em titulações e química analítica. As considerações de segurança incluem manuseá-lo com cuidado, pois a exposição excessiva pode levar a irritação ou outros problemas de saúde. No geral, Iodeto de potássio é um composto versátil com importância significativa tanto na saúde quanto na pesquisa científica.

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.

Produto descontinuadoPotassium iodide
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.Fórmula:IKPureza:Min 99%Cor e Forma:White Off-White PowderPeso molecular:166 g/molPotassium iodide, 99+% (ACS)
