  • Method for monitoring in peptide synthesis
    Patent number: 5262331
    Abstract: A method for monitoring the reaction between an activated carboxylic acid derivative and an amine, such as the formation of a peptide bond in peptide synthesis, whereby an inert anionic dye component and an inert cationic component are included in the reaction system, in small relative amounts compared to the carboxylic acid derivative. The distribution of the dye component to the cationic component, when separated from the amine component, is monitored and at a given maximum value indicates a substantially quantitative reaction.
