Add excess silylating reagent (e.g., BSTFA + 1% TMCS). The reagent can be used at full strength or with a solvent.* In most applications it is advisable to use an excess of the silylating reagent – at least a 2:1 molar ratio of reagent to active hydrogen. In most cases 1% TMCS in BSTFA is sufficient to achieve the desired derivatization. 3. trail to blacks beach
