LabChem® Diphenylcarbazone-Bromophenol Blue

LabChem® DIPHENYLCARBAZONE-BROMOPHENOL BLUE is a pre-mixed indicator solution combining diphenylcarbazone with bromophenol blue for use in the mercurimetric titration of chloride. Blending both indicators in a single, fixed-ratio solution produces a sharper, easier-to-see endpoint color change than diphenylcarbazone alone. Its pre-mixed formulation ensures a consistent, accurate addition every time.

It is commonly used as the indicator in the mercuric nitrate titration method for chloride determination in water and wastewater testing. Its consistent formulation supports reliable, reproducible endpoint detection across testing sessions. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
