Abstract

3-Chloro-3-[2′, 3′(CO), 6′, 5′(CO)dibenzoylene-4′-pyridyl]phthalide (Dibepin-2) is an analytical color reagent for primary aliphatic amines and arylalkylamines (with the exception of ethylenediamine and 1, 2-diaminopropane). The reaction is always negative with secondary and tertiary amines.
