N,O-Bis(trimethylsilyl)trifluoroacetamide (CAS 25561-30-2)

N,O-Bis(trimethylsilyl)trifluoroacetamide, often referred to by its abbreviation BSTFA, is a reagent widely employed in the field of analytical chemistry, particularly in gas chromatography-mass spectrometry (GC-MS) analyses. N,O-Bis(trimethylsilyl)trifluoroacetamide is used for the derivatization of a wide range of compounds containing hydroxyl, amine, or carboxyl groups, which increases their volatility and thermal stability, thereby making them more amenable to GC-MS analysis. Researchers utilize N,O-Bis(trimethylsilyl)trifluoroacetamide to study the chemical composition of complex mixtures and to identify trace organic compounds in environmental samples, forensic investigations, and metabolomics. The silylation process introduced by N,O-Bis(trimethylsilyl)trifluoroacetamide is essential for the accurate quantification of compounds that would otherwise be difficult to analyze due to their polar nature. Studies involving N,O-Bis(trimethylsilyl)trifluoroacetamide derivatization provide insights into the molecular structure and properties of analytes. It is also used in the preparation of samples for the identification of unknown substances or the determination of known compounds in various matrices.
