Used as a derivatization agent in analytical chemistry to enhance the detection and quantification of compounds in gas chromatography and mass spectrometry. It is particularly effective in converting polar compounds, such as alcohols and amines, into more volatile and thermally stable derivatives, improving their analytical performance. Commonly applied in the analysis of pharmaceuticals, environmental samples, and biological fluids due to its ability to provide accurate and reproducible results. Additionally, it is utilized in proteomics for the modification of amino acids and peptides, aiding in their identification and structural analysis.
