Used primarily as a matrix in MALDI (Matrix-Assisted Laser Desorption/Ionization) mass spectrometry, especially for the analysis of hydrophobic and large biomolecules such as membrane proteins, lipids, and synthetic polymers. Its strong absorption in the UV range enhances ionization efficiency, providing clearer and more sensitive detection. Particularly effective for high-mass compounds that are difficult to ionize with conventional matrices. Also shows improved performance in imaging mass spectrometry due to reduced background interference and better crystal homogeneity on tissue surfaces.
