MtBSTFA

Category: Silylation Reagents
CAS # : 77377-52-7
Chemical Name: N-tert-Butyldimethylsilyl-N-methyltrifluoroacetamide + 1% tert-Butylchlorodimethylsilane
Description:

MtBSTFA replaces active hydrogens to form t-BDMS derivatives. Derivatization is usually complete upon dissolution with this exceptionally strong, yet mild silylating reagent. MtBSTFA derivatives are 104 times more stable to hydrolysis than their corresponding TMS derivatives and produce easily interpreted mass spectra for GC/MS. Addition of t-BDMCS catalyzes reactions of hindered alcohols and amines.
