Abstract
An accurate and precise fluorometric procedure was developed for the determination of histidine based on the observation that o-phthalaldehyde forms a fluorophor with the analogous compound, histamine. The precision of the method was improved, and the fluorophor was stabilized for days by the addition of a phosphoric acid reagent.Keywords
