WebDescription. α-cyano-4-hydroxycinnamic acid (CHCA) is a recrystallized matrix for matrix-assisted laser desorption ionization (MALDI) mass spectrometry. Ultrapure CHCA matrix produces homogeneous crystals that lead to MALDI mass spectra with excellent resolution, high sensitivity, and high S/N ratios. * This product is For Research Use Only. WebSep 1, 2003 · Some benzoic acid and cinnamic acid derivatives have been found to be good MALDI matrices. In particular, 2,5-dihydroxybenzoic acid (DHB) [12] and α-cyano-4-hydroxycinnamic acid (CHCA) [13] have become favored matrices for the analysis of peptides and small proteins.
