High Potassium Content – Effectively supplies potassium to support plant growth and prevent crop diseases.
Medical Benefits – Widely used to treat hypokalemia by maintaining proper potassium levels in the body.
Food-Grade Versatility – Functions as an electrolyte replenisher and a healthy salt substitute in food products.
Texture Enhancement – Acts as a firming agent to improve food structure and consistency.
Potassium Chloride CAS# 7447-40-7
Potassium chloride (KCl) is a metal halide salt with a wide range of applications. Its primary use is as a fertilizer, supplying essential potassium to plants and helping protect them from certain diseases. In addition, it is utilized in the food and pharmaceutical industries. In medicine, potassium chloride tablets are commonly used to treat hypokalemia by restoring and maintaining normal potassium levels in the blood. In the food industry, it functions as an electrolyte replenisher, an effective salt alternative, and a firming agent that improves food texture and structural stability.

Product Usage (Rewritten):
Potassium chloride (KCl) is widely used in pharmaceutical formulations, food additives, and as a chemical reagent. Replacing table salt (sodium chloride) with potassium chloride can help lower dietary sodium intake and may offer health benefits. In addition, molten potassium chloride is utilized in the electrolytic production of metallic potassium. KCl is naturally present in seawater brine and can also be obtained through extraction from the mineral carnallite.
