N-t-Butyldimethylsilylimidazole Product Specification N-t-Butyldimethylsilylimidazole (TBDMSIM) is formed by reacting butyldimethylchlorosilane and imidazole (1:2). Although TBDMSIM is not widely used, the t-butyldimethylsilyl (TBDMS) derivatives it forms enhance thermal stability and increase the inertness of the analyte(s). A weak silylating reagent, TBDMSIM…
