D(4)-α-Cyano-4-hydroxycinnamic acid (D(4)-CHCA) has been synthesized for use as a matrix for matrix-assisted laser desorption ionization-mass spectrometry (MALDI-MS) and MALDI-MS imaging (MSI) of small molecule drugs and endogenous compounds. MALDI-MS analysis of small molecules has historically been hindered by interference

What can be used for solublization of α-Cyano-4-hydroxycinnamic acid?
1 answer-
α-Cyano-4-hydroxycinnamic acid (α-CCA, α-CHCA, α-Cyano, 4-HCCA, ACCA) is soluble in methanol (up to 50 mg/ml). It is also soluble at 10 mg/ml using 50% acetonitrile in 0.05% TFA for MALDI-MS. The acetonitrile concentration can be adjusted for individual preferences.For biological applications, it has been solubilized at 100 mM in DMSO or 50 mM in ethanol.
