Introduction
Correct the acidity of urine. Polyvalent complexing agent, a polyvalent chelating agent that removes trace metals. Buffer, bacterial medium.
Application
Sodium citrate (CAS 68-04-2), the trisodium salt of citric acid, is a versatile organic compound widely used as a buffering agent, emulsifier, and anticoagulant. In the pharmaceutical industry, it is employed as an anticoagulant in blood collection tubes and apheresis procedures, as a urine alkalinizer to prevent kidney stones, and as a tablet effervescent agent. In food applications, it acts as a pH regulator, preservative, and melting salt for processed cheese (e.g., sodium citrate E331). It is also used in beverages to control acidity and enhance flavor. In cosmetics and personal care, sodium citrate functions as a chelating agent and pH adjuster in creams, lotions, and shampoos. Additionally, it serves as a water softener in detergents, a corrosion inhibitor in electroplating, and a plaster retarder in construction. Its high purity grade ensures consistent performance in all applications.
