Potassium iodide is used in pharmaceutical formulations and in film photography as a source of iodine. It is widely used as an analytical Reagent in iodometric tritrations. Apart from its application as a source of iodide to produce organo iodine compounds such as in Sandmeyer reactions, potassium iodide finds extensive use as a nucleophilic catalyst for several alkylation reactions.

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.

Applications
Potassium iodide is used in pharmaceutical formulations and in film photography as a source of iodine. It is widely used as an analytical Reagent in iodometric tritrations. Apart from its application as a source of iodide to produce organo iodine compounds such as in Sandmeyer reactions, potassium iodide finds extensive use as a nucleophilic catalyst for several alkylation reactions.

Solubility
Soluble in water

Notes
Being a mild reducing agent, it gets converted into iodine by oxidizing reagents. Potassium iodide should be handled with gloves since it is a mild irritant.
