1,4-Dihydroxy-2-butanone（Cat No.:M068421）, commonly known as DHB, is a chemical compound with a molecular structure consisting of a butanone backbone with hydroxyl groups attached at the 1st and 4th positions. Also referred to as ribose, it serves as a crucial component in the matrix-assisted laser desorption/ionization (MALDI) process, aiding in the ionization of analytes during mass spectrometry. DHB’s ability to efficiently absorb laser energy and transfer it to analytes makes it a widely used matrix in MALDI mass spectrometry for the analysis of peptides, proteins, carbohydrates, and other biomolecules in various research fields, including proteomics and metabolomics.
