Product Details
Potassium chloride CAS#7447-40-7
Potassium chloride (KCl) is a metal halide salt with wide industrial and commercial applications. Its most common use is as a fertilizer to supply potassium to crops and help protect plants from diseases. It also plays important roles in food and pharmaceutical fields. For medical purposes, potassium chloride tablets are used to manage hypokalemia, maintain proper blood potassium concentrations, and avoid potassium deficits. In food processing, it acts as an electrolyte replenisher, a common salt substitute, and a firming agent that improves food texture and structural stability.

Product Application
Potassium chloride CAS#7447-40-7
Potassium chloride is extensively used in both injectable and non-injectable pharmaceutical products. Its key medical applications include preparing isotonic solutions for injection and ophthalmic use. It is also a standard therapeutic agent for hypokalemia. Various solid dosage forms are available, such as direct-compression tablets, granule tablets, effervescent tablets, delayed-release and sustained-release tablets, microcapsules, pellets, and osmotic pump systems. In pharmaceutical research, potassium chloride is often used as a model drug for developing new sustained-release and modified-release formulations. In the food industry, it serves as a nutrient supplement, pH adjuster, stabilizer, thickener, and gelling agent, and is suitable for use in infant formulas.
