Pharmaceutical Chemistry
Potassium chloride
Formula:
KCl
GOST/CAS:
CAS 7447-40-7
Potassium chloride (pharmaceutical grade) is a high-purity mineral component that serves as an essential source of potassium ions (K+) for the human body. The product is a white, crystalline powder or colorless crystals, odorless and freely soluble in water. Due to its strictly controlled absence of impurities and highly stable chemical composition, this product is indispensable in the manufacture of infusion solutions, oral medications, dietary nutrition, as well as in laboratory and biotechnological applications.
Applications
Infusion and Injection Manufacturing: Used as an Active Pharmaceutical Ingredient (API) for preparing sterile systemic solutions (including saline and polarizing solutions) to correct electrolyte balance.
Solid Dosage Forms: Applied in the compression of tablets, capsules, and granules designed to replenish potassium deficiency in the body due to hypokalemia of various origins.
Pharmaceutical Synthesis and Biotechnology: Serves as a nutrient medium and buffering component for cultivating microorganisms and cell cultures in the production of antibiotics and vaccines.
Dietary and Therapeutic Nutrition: Formulated into specialized products, sports nutrition, and low-sodium salt substitutes for patients with arterial hypertension.
Key Advantages
Exceptional Purity (Ph. Eur. / USP): Fully complies with the stringent requirements of international and national pharmacopoeias. It boasts a maximum assay of the main substance with strict limits on heavy metals, arsenic, and sulfates.
High Bioavailability: Dissociates rapidly into ions in liquid environments, ensuring immediate therapeutic action and precise dosing in finished medicinal products.
Stability and Compatibility: Resistant to hydrolysis, withstands thermal sterilization (autoclaving) within solutions, and blends perfectly with other salts (sodium, magnesium, calcium) and glucose.
Safety and Hypoallergenicity: Demonstrates zero toxicity when technological standards are maintained; it is fully biocompatible and safe for manufacturing medications for all age groups.
Storage & Transportation
- Store in dry, cool, and well-ventilated warehouses in tightly closed original packaging, protected from light.
- The product is hygroscopic, so it must be protected from direct moisture exposure and stored at a relative air humidity not exceeding 65-70%.
- Transportation is permitted by all types of covered transport under temperature conditions that prevent sudden fluctuations (to avoid caking and clumping).
- The material is not classified as a dangerous good (ADR/GGVS is not applicable). Shelf life is 3 years from the date of manufacture.
