3,5-DiBr-PAESA sodium

Overview

3,5-DiBr-PAESA sodium is a water-soluble pyridylazo-based highly sensitive chromogenic reagent. With the assistance of EDTA for masking copper and bromide ions for dissociating silver chelates, 3,5-DiBr-PAESA sodium enables accurate determination of sub-milligram level silver ions in strongly acidic high-copper systems via flow injection spectrophotometry.
