Potassium

Potassium (CAS 7440-09-7), also known as Kalium, is an alkali metal supplied industrially in refined elemental form for use as a reactive reducing agent and chemical intermediate. In food, pharmaceutical, and agricultural contexts, it functions primarily as a source of potassium ion activity.

This material supports nutrient fortification, electrolyte balance, and crop nutrition programs across various sectors. In pharmaceutical manufacturing, elemental potassium serves as a precursor in synthesizing potassium-based active ingredients and excipients where controlled reactivity is required.

Food and nutrition producers use potassium-derived compounds for mineral fortification in functional foods, dietary supplements, and electrolyte formulations targeting potassium intake. These applications ensure that essential mineral levels are maintained in consumer products.

In agriculture, it underpins the production of potassium fertilizers that correct soil deficiencies and support yield in potassium-sensitive crops. Industrial chemical synthesis also draws on elemental potassium as a strong reducing agent in specialty organic reactions.

Elemental potassium is supplied as a metal in sealed, inert-atmosphere packaging due to its high reactivity with moisture and air. It is typically provided as ingots, lumps, or dispersions in mineral oil to ensure safe handling and storage.

Technical and reagent grades are the standard commercial forms available for industrial procurement. Purity specifications vary by application, with high-purity grades available for pharmaceutical and specialty chemical use to meet rigorous industry requirements.
