General description
α-Cyano-4-hydroxycinnamic acid (CHCA) is specially purified and qualified as a matrix for peptide MALDI-MS (matrix assisted laser desorption ionization-mass spectrometry) calibration standards. CHCA enhances ionization of protein or peptide standards and samples in matrix assisted laser desorption ionization (MALDI) mass spectrometers.[1][2]
It is also available as part of our ProteoMass™ MALDI calibration kits (MS-CAL1 and MS-CAL3).
