      Product Detail  


    Chemical Name:   Trimethylsilyl iodide

    Synonyms : Trimethylsilyl iodide;Iodotrimethylsilane;TMIS;TMSI;Trimethyliodosilane

    CAS N o:   16029-98-4

     

    Priary Use : Organic synthesis reagent: dealkylation/cleavage of ethers, esters, carbamates, ketals, lactones; introduction of the trimethylsilyl (TMS) protecting group to alcohols etc., forming silyl ether derivatives (e.g. for GC derivatization to increase volatility).Deprotection & selective reactions: selective removal of protecting groups such as N-Cbz where other deprotections fail; acts as a Lewis-acid catalyst and reducing agent in many organic transformations.Pharma & materials intermediate: an important intermediate for synthesizing cephalosporins such as ceftazidime; also used to prepare organosilicon compounds and silylating agents.Stabilizer: commercial material is usually stabilized with Cu (~0.1%) or Al to suppress decomposition and free-iodine formation, improving storage stability.
