A series of small peptides has been studied by negative‐ion fast‐atom bombardment mass spectrometry with collision‐induced dissociation. It has been found that by derivatizing peptides with 4‐aminonaphthalenesulphonic acid in a peptide linkage at the C‐terminus, negative‐ion formation can be enhanced and fragmentation in collision‐induced dissociation reactions controlled. The peptide‐naphthalenesulphonates show charge‐remote fragmentations and the resultant spectra give sequence information.
