Used primarily as a derivatization agent in analytical chemistry, particularly in gas chromatography-mass spectrometry (GC-MS). It aids in the detection and quantification of compounds by enhancing their volatility and thermal stability, making them easier to analyze. Commonly applied in the analysis of steroids, amino acids, and other organic compounds, it improves sensitivity and resolution in chromatographic separations. Additionally, it is employed in the preparation of samples for environmental, pharmaceutical, and biomedical research, ensuring accurate and reliable results.
