title: Development of a temporary marker for peptides.
abstract: 3-[(N,N-Dimethylaminophenyl)-4'-diazenyl]benzoic acid was coupled with several amino acid esters and the product acylated further with Boc. The material thus obtained was then submitted to cleavage by electrolysis and nucleophilic attack in order to evaluate the possibility of using this chromophore as a temporary marker.
