Popis

General description

Trifluoroacetic acid (TFA) is a nonaqueous solvent. At room temperature, TFA has the ability to liquify native and regenerated celluloses.

Application

Bruker standard solvent can be used in sample preparation and calibration for matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), ensuring accurate identification of pathogenic bacteria from clinical positive blood cultures.

Biochem/physiol Actions

Trifluoroacetic acid (TFA) is mainly preferred as an internal chemical shift referencing agent in 19F NMR.
