Description

Calcium Trisodium Pentetate is a high-purity chelating agent and sequestrant, primarily recognized for its strong affinity for polyvalent metal ions. This compound is critical for ensuring product stability and process efficiency by effectively controlling metal ion contamination. It is essential for manufacturers in the pharmaceutical, food, and industrial sectors requiring reliable metal deactivation and purification.

Application

• Pharmaceutical Manufacturing: Used as a stabilizing agent in injectable formulations and diagnostic kits to chelate trace metals that can catalyze degradation.
• Food & Beverage Industry: Acts as a sequestrant and preservative to maintain color, flavor, and shelf-life stability in processed foods and beverages.
• Industrial Water Treatment: Employed in boiler and cooling water systems to prevent scale formation by sequestering calcium, magnesium, and other metal ions.
• Cosmetics & Personal Care: Functions as a chelating agent in creams, lotions, and shampoos to enhance stability and protect against rancidity caused by metal impurities.
• Chemical Synthesis & Catalysis: Serves to deactivate metal catalysts or purify reaction mixtures in fine chemical and API synthesis.
• Laboratory & Analytical Reagents: Used in buffer solutions and analytical methods for complexometric titrations and metal ion analysis.

Quality Control

Our Calcium Trisodium Pentetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, purity, and specific impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed immediately after use to prevent moisture absorption, which can affect product stability and handling properties.
