Description

Ethanoldiglycine Disodium Salt is a high-purity chelating agent and chemical intermediate essential for processes requiring precise metal ion control. Its primary value lies in its strong sequestering ability for di- and trivalent metal ions, which is critical for maintaining product stability and process efficiency. This compound is particularly vital for manufacturers in the pharmaceutical, cosmetic, and industrial cleaning sectors who require reliable, high-quality raw materials for formulation and synthesis.

Application

• Pharmaceutical Synthesis: Used as a key intermediate or buffering/chelating agent in the production of active pharmaceutical ingredients (APIs) and diagnostic reagents.
• Cosmetic & Personal Care Formulations: Acts as a stabilizer and chelating agent in creams, lotions, and other products to prevent degradation caused by metal ion contamination.
• Industrial Cleaning & Detergents: Enhances the performance of cleaning formulations by sequestering water hardness ions (like calcium and magnesium), improving surfactant efficacy.
• Chemical Manufacturing: Serves as a specialized chelator in various chemical synthesis and catalytic processes where metal ion purity is paramount.
• Laboratory & Research: Employed as a standard or reagent in biochemical and analytical research for studying metal-ligand interactions.
• Water Treatment: Functions as a component in specialty water treatment formulations to control scale and corrosion.

Quality Control

Our Ethanoldiglycine Disodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and industrial applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, loss on drying, and heavy metal content. We can supply material compliant with various pharmacopoeial standards (e.g., USP, EP, BP) upon request.

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 after opening to minimize exposure to atmospheric moisture, which can affect product quality and handling.
