Potassium Chloride Extra Pure
$ 18.20
Potassium Chloride Extra Pure is a high-purity, crystalline inorganic salt with the chemical formula KCl. It appears as a white, odorless, and highly soluble solid, widely used across laboratory, medical, and industrial applications due to its chemical stability and essential role in biological systems.
In laboratory settings, it serves as a reagent in buffer solutions, electrolyte standards, and ionic strength adjustment. In biochemistry, it’s frequently used to prepare isotonic solutions and simulate intracellular fluid composition. Its high purity ensures accuracy in molecular biology, analytical chemistry, and instrument calibration.
Industrially, Potassium Chloride is vital in fertilizer production (as potash), water softening systems, and food processing (as a sodium-free salt alternative).
Potassium Chloride Extra Pure
PRIMARY USES
- Laboratory Reagent:
- Used as a source of potassium ions (K⁺) and chloride ions (Cl⁻) in chemical experiments and buffer solutions.
- Commonly used in calibration of conductivity meters and preparation of standard solutions.
- Pharmaceuticals & Medical:
- Acts as an electrolyte replenisher in IV fluids and oral rehydration solutions.
- Treats or prevents hypokalemia (low potassium levels in blood).
- Food Industry (in food-grade form):
- Used as a salt substitute (partial replacement for sodium chloride) in low-sodium diets.
- Helps in maintaining mineral balance in processed foods.
SECONDARY USES
- Agriculture & Fertilizers:
- Major component in potash fertilizers to provide potassium, vital for plant growth.
- Water Treatment:
- Used to regenerate water softeners, especially in chloride-sensitive applications.
- Industrial & Chemical Manufacturing:
- Used in production of potassium hydroxide, potassium metal, and other inorganic compounds.
