Widely used as a matrix in MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight) mass spectrometry, especially for the analysis of peptides and proteins. It effectively absorbs laser energy and facilitates ionization with minimal fragmentation, providing clear and reproducible mass spectra. Its solubility in common organic solvents and compatibility with biological samples make it ideal for proteomics research and biomolecule characterization. Often preferred for its ability to produce high signal-to-noise ratios in the low molecular weight range.
