Abstract The utility of benzoyl and pentadeuterobenzoyl derivatives of peptide methyl esters for mass spectrometric analysis was investigated. The mass spectra of the glu‐his and the val‐tyr‐pro derivatives are discussed. Treatment of the peptide methyl esters with the mixed benzoic‐ethyl‐carbonic anhydride did in some cases lead to benzoyl derivatives as well as to ethoxycarbonyl derivatives.
