Abstract
The utility of ethoxycarbonyl-peptide methyl esters for mass spectrometric analysis is described. The ethoxycarbonyl group has important advantages over other protecting groups which are in use. The derivatives have high intensity; this greatly facilitates the interpretation of the fragmentation pattern. The spentra of the methyl esters of the ethoxycarbonyl derivatives of pro-val, trp-gly, gly-ser, (cys)2, glutation (GSH), glu-his-phe, val-tyr-pro and val-lys-val-tyr-pro are given.
