Widely used as a matrix in MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight) mass spectrometry, enabling the analysis of large biomolecules like peptides and proteins. It absorbs laser energy efficiently and facilitates ionization with minimal fragmentation, making it ideal for generating clear mass spectra. Commonly chosen for its ability to dissolve well in common organic solvents and co-crystallize with analytes, ensuring uniform sample distribution on the target plate. Also used in some UV-protective materials due to its strong absorption in the ultraviolet range.
