WebSecondary -OH groups also react efficiently in 20-100% BSTFA, but the reaction yield improves slightly when trimethylchlorosilane (TMCS) is added as a catalyst. Reaction of tertiary -OH groups with BSTFA was very inefficient, but improved with addition of 10% TMCS to the BSTFA solution. Finally, -COOH groups seemed to react most efficiently … WebPrinciple byproduct from the derivatization reaction is N-methyltrifluoroacetamine, which is stable, volatile and does not present problems in subsequent GC ...

WebBSTFA is a powerful thrimethylsilyl donor, with donor strength that is comparable to its unfluorinated analog BSA [N,O-Bis (trimethylsilyl)acetamide]. BSTFA reacts to replace … WebThe resulting material can be further silylated using BSTFA as shown in the reaction: Numerous other analyses using derivatization by silylation were reported for the analysis of phospholipids [15]. Among other derivatizations, phosphoric acid esters with active hydrogens can be derivatized using the formation of a phosphoroamide as follows: ... WebFeb 15, 2024 · Optimization of the derivatization reaction. Derivatization was carried out by three reagents: MBTFA, BSTFA, and MSTFA. Derivatization reaction was optimized at different reaction temperatures and reaction times. The reaction was carried out at 80 °C and 100 °C for 45 and 60 min. Five replicate analyses were done for each set. hospitalist board
