Cas no 7778-80-5 (Potassium Sulphate)
Potassium Sulphate (K?SO?) is a high-purity inorganic salt widely used as a fertilizer and industrial reagent. It provides essential potassium and sulfur nutrients, promoting plant growth without chloride-related toxicity. Its low solubility and neutral pH make it suitable for sensitive crops and precision applications. The compound is also employed in glass manufacturing and analytical chemistry.
