Description

Glycine, N,n-1,2-Ethanediylbis-, Disodium Salt is a high-purity chelating agent and chemical intermediate, also known as EDTA disodium salt. This compound is critical for binding and sequestering metal ions, ensuring stability and performance in complex formulations. It is an essential raw material for manufacturers in the pharmaceutical, personal care, and industrial cleaning sectors who require reliable metal ion control.

Application

• Pharmaceutical Manufacturing: Used as a stabilizing agent in injectable and ophthalmic solutions to chelate trace metals that can catalyze degradation.
• Cosmetics & Personal Care: Acts as a sequestrant in shampoos, creams, and lotions to improve product shelf life and prevent rancidity.
• Industrial Cleaning & Detergents: Enhances the efficacy of cleaning formulations by softening water and inactivating metal ions that interfere with surfactants.
• Food & Beverage Processing: Employed as a preservative and color/ flavor stabilizer in certain food-grade applications where permitted.
• Laboratory & Analytical Chemistry: Serves as a key component in buffer solutions and as a titrant in complexometric titrations.
• Agriculture & Micronutrient Formulations: Used in chelated micronutrient fertilizers to improve plant uptake of essential metals like iron and zinc.

Quality Control

Our Glycine, N,n-1,2-Ethanediylbis-, Disodium Salt is produced under a strict quality management system. We offer grades compliant with USP, EP, BP, and FCC monographs where applicable. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting purity, heavy metals, and other critical parameters are available upon request to ensure your quality and regulatory compliance.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
