Description

For the colorimetric determination of Mn (oxidizes manganese compounds to permanganates), as oxidizing agentPotassium periodate is used as an oxidizing agent in organic synthesis and an analytical reagent for the determination of potassium and cerium. It is also used in colorimetric estimation of manganese. It reacts with ammonium cerium(IV) nitrate to prepare tris[trinitratocerium(IV)] paraperiodate which finds application as an oxidant.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
