Ultrapure MALDI Matrix α-Cyano-4-hydroxycinnamic acid (CHCA) is a commonly used MALDI mass spectrometry (MALDI-MS) reagent with a λmax at 337 nm and 355 nm. CHCA is a good first choice for MALDI-MS to use with proteins and peptides less than 10 kDa. Dissolve right in the plastic tube to get your saturated matrix solution!
