TMSI

 
TMSI is a Silylation Reagent for GC Derivatization and is a potent, selective TMS donor that reacts with alcohols and phenols, but not amines or amides. TMSI derivatizes wet sugar samples, hindered hydroxyl groups in steroids, and amino acids in fluorinated acylation reagents. TMSI is used in the preparation of dual perfluoroacyl and TMS derivatives.
