Abstract
A rapid high-performance liquid chromatographic method for determination of the dansyl derivative of pentaazapentacosane (PAPC) pentahydrochloride has been developed. The chromatographic system uses a reversed-phase C8 column, a mobile phase of acetic acid buffer and acetonitrile and UV detection. The dansylation conditions were optimized with a pH of 11.0 and a 20-fold dansyl chloride excess. The yield of dansyl PAPC increased 10-fold as the reaction pH was changed from 9.5 to 10.5. Under derivatization conditions of pH 8.5-11.0 and 1-30-fold excess dansyl chloride only perdansyl PAPC was found.
