Description

(Ethylenediaminetetraacetato)Calcium(2-) is a calcium chelate of ethylenediaminetetraacetic acid (EDTA), a highly stable coordination compound. This product is valued for its ability to effectively sequester metal ions, making it a critical component in processes requiring precise control over metal contamination. It serves as a key ingredient for formulators and manufacturers in the pharmaceutical, food, and industrial sectors who require a reliable, high-purity chelating agent.

Application

• Pharmaceutical Manufacturing: Used as a stabilizing agent and metal ion scavenger in injectable formulations, ophthalmic solutions, and topical products to enhance shelf-life and efficacy.
• Food & Beverage Industry: Functions as a preservative and sequestrant to prevent catalytic oxidation, maintaining color, flavor, and nutritional value in canned goods, dressings, and beverages.
• Cosmetics & Personal Care: Employed in creams, lotions, and shampoos as a chelating agent to improve product stability by inactivating trace metals that can cause rancidity or discoloration.
• Industrial Cleaning & Water Treatment: Acts as a key component in boiler and cooling water treatment formulations to control scale and corrosion by binding calcium and magnesium ions.
• Laboratory & Analytical Chemistry: Serves as a primary standard and complexometric titrant in analytical procedures for the determination of various metal ions.
• Agricultural Formulations: Used in micronutrient fertilizers and pesticide formulations to improve the bioavailability and stability of essential metal ions.

Quality Control

Our (Ethylenediaminetetraacetato)Calcium(2-) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure compliance with relevant industry standards, including USP-NF and FCC specifications where applicable. A comprehensive Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is available for every shipment to guarantee traceability and consistency for your critical applications.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
