What are the applications of Application
4-(2-Thiazolylazo)resorcinol is a dye used in the spectrophotometric determination of trace metals
Purification Methods
Dissolve it in aqueous alkali, extract it with diethyl ether, and re-precipitate it with dilute HCl. The purity is checked by TLC on silica gel using pet ether/diethyl ether/EtOH (10:10:1) as the mobile phase. It complexes with Cu2+ (pH 3-4), Co2+ and Ni2+ (pH 7) and Zn2+ , andCd2+ (pH 8.4).
