Descrição

Descrição geral

Sodium iodide is an inorganic sodium salt that is commonly used as a source of iodide ions in organic synthesis. It is used in the conversion of alkyl halides and sulfonates into alkyl iodides and aryl iodides via nucleophilic displacement reactions. Additionally, NaI is also used in combination with oxidizing agents for the iodination of organoboranes, phenols, and aromatic compounds.

Aplicação

Sodium iodide can be used in the following:      

• NaI-AlCl₃ is used as a dehydrating agent in the Beckmann rearrangement of ketoximes to anilides.      
• NaI-cerium chloride supported on silica gel is used as a catalyst for the synthesis of 2,3-dihydro-1H-1,5-benzodiazepines by the reaction of o-phenylenediamines and ketones.      
• NaI-dichlorodimethylsilane catalytic system is used for the reduction of diarylmethanols to corresponding diarylmethanes.

Características e benefícios

• Increased efficiency – Eliminates time and effort of loosening hardened powders     
• Safety – Eliminates tools of force used to break up clumps
• Ecology – Reduces waste as it does not stick to the packaging      
• Economy – Faster preparation and solvation increase productivity and reduce costs      
• Assured Quality – Excellent, expert-tested quality with no anti-caking agents      
• Flexible volumes – Available from research amounts to scale-up quantities
