Used primarily as a derivatization reagent in analytical chemistry, especially in mass spectrometry. It helps detect and characterize carbonyl-containing compounds such as aldehydes and ketones by forming stable oxime derivatives. This enhances sensitivity and selectivity during analysis. Also employed in metabolic profiling and biomarker discovery due to its ability to tag reactive carbonyl species in biological samples. Its fluorinated structure improves chromatographic separation and detection through fluorine-specific techniques. Additionally, it serves as a building block in the synthesis of pharmaceutical intermediates where selective protection or functional group modification is required.
