Description

Ammonium Dihydrogencitrate is the ammonium salt of citric acid, a versatile organic compound widely used in industrial and technical applications. Its primary value lies in its ability to function as a buffering agent, acidity regulator, and metal chelator, offering a safer and more soluble alternative to free citric acid in certain formulations. This product is essential for manufacturers in the food, pharmaceutical, and chemical synthesis sectors who require precise pH control and sequestering properties.

Application

• Food & Beverage Industry: Used as an acidity regulator, pH buffer, and sequestrant in beverages, jams, and dairy products.
• Pharmaceutical Manufacturing: Serves as an excipient in tablet and capsule formulations, acting as a disintegrant and buffering agent.
• Industrial Cleaning & Descaling: An effective, biodegradable component in cleaning agents for removing limescale and rust from metal surfaces.
• Chemical Synthesis: Employed as a catalyst or a mild acid source in various organic synthesis reactions.
• Water Treatment: Functions as a chelating agent to control metal ion concentrations in boiler and cooling water systems.
• Laboratory & Analytical Reagents: Used in the preparation of buffer solutions for biochemical and analytical procedures.
