Description

General description

2,6-Dichloroquinone-4-chloroimide generally find application in being used as spot test and chromatographic spray reagents, mainly for phenols, though it can be used in detection of other types of compounds such as antioxidants, few primary and secondary amines, on silica gel chromatographic plates. Its decomposition rate is directly proportional to pressure.

Application

Gibb′s reagent was used in paper chromatography, in an experiment conducted to semi-quantitatively estimate tyramine and octopamine.
