Description

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.
It is also available as part of our ProteoMass^™ MALDI calibration kits (MS-CAL1 and MS-CAL3).

Application

α-Cyano-4-hydroxycinnamic acid has been used as a matrix for MALDI-TOF MS (matrix assisted laser desorption ionization-time of flight mass spectrometry) analysis. The matrix has also been used for sample preparation.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
