Product Name:N,O-Bis(trimethylsilyl)trifluoroacetamide
English Name:N,O-Bis(trimethylsilyl)trifluoroacetamide
CAS No.:25561-30-2
Aliases:BSTFA, N,O-Bis(trimethylsilyl)trifluoroacetamide
Molecular Formula:C8H18F3NOSi2
Physical Properties:Colorless to light yellow transparent liquid with a pungent odor; density 0.969 g/mL at 25°C, boiling point 45-50°C at 12 mmHg, flash point approximately 23°C; moisture-sensitive and decomposes upon contact with water; soluble in organic solvents such as dichloromethane and chloroform; store sealed under a dry inert atmosphere.
Uses:Widely used as a silylation derivatization reagent in GC/MS analysis for the trimethylsilylation of compounds containing active hydrogen, such as alcohols, phenols, carboxylic acids, amines, amino acids, and sugars, thereby improving sample volatility and thermal stability and enhancing chromatographic separation. It is also employed as a trimethylsilyl protecting agent or silylation intermediate in organic synthesis.
Technical Specifications:
Purity ≥ 99%
Molecular weight 257.4
Appearance: colorless transparent liquid
Density 0.969 g/mL at 25°C
Storage at 2-8°C, sealed and dry
