Description

Potassium Citrate is the potassium salt of citric acid, a white, crystalline powder widely recognized for its buffering, alkalizing, and sequestering properties. Its primary commercial value lies in its ability to precisely control pH and act as a safe, effective source of bioavailable potassium. This essential compound is a critical raw material for manufacturers in the pharmaceutical, food and beverage, and industrial sectors seeking reliable, high-purity ingredients.

Application

• Pharmaceuticals: Used as an alkalizing agent in oral and urinary preparations, and as an active pharmaceutical ingredient (API) in potassium supplements and effervescent tablets.
• Food & Beverage Additive (E332): Functions as a buffering agent, stabilizer, and sequestrant in soft drinks, jellies, dairy products, and low-sodium foods.
• Industrial Applications: Serves as a buffering agent in electroplating solutions, a dispersant in ceramic and cement production, and a component in specialty detergents and cleaning formulations.
• Laboratory & Research: Employed as a reagent in biochemical research and as a standard in analytical chemistry.
