INTRODUCTION

Ferrozine, chemically 3-(2-Pyridyl)-5,6-bis(4-phenylsulfonic acid)-1,2,4-triazine disodium salt, is a water-soluble solid. It is complexometric reagent for detection and estimation of iron.

Manufacture
It is synthesized by condensation of 2,6-dimethyl pyridine with 3,5-dinitrobenzenesulfonic acid, followed by reduction with Fe powder, and then sulfonation with fuming sulfuric acid. Purification occurs via crystallization from water.
