ABSTRACT:
A method for quantitatively measuring an acid in a polar organic solvent involves adding a sterically hindered base, such as diisopropylentylamine, triethylamine or N-methylmorpholine to the solvent and measuring the conductance of the mixture. The method has particular relevance in monitoring the progress of preactivation, coupling and deprotection reactions in solid phase peptide synthesis (SPPS).
