Description

Glycine, N,n-Bis2-Bis(Carboxymethyl)Aminoethyl-, Pentapotassium Salt is a high-purity, water-soluble chelating agent and a pentapotassium salt derivative of a polyaminocarboxylic acid. This compound is valued for its exceptional ability to sequester and deactivate di- and trivalent metal ions, preventing unwanted precipitation and catalytic activity in sensitive formulations. It is essential for manufacturers in industries requiring precise metal ion control, such as pharmaceuticals, analytical chemistry, and specialty cleaning. The product is supplied as a high-quality material to ensure consistent performance in critical applications.

Application

• Pharmaceutical Manufacturing: Acts as a stabilizing agent and metal chelator in injectable formulations and buffer solutions to enhance shelf-life.
• Analytical Chemistry & Diagnostics: Used as a key component in buffer systems for electrophoresis, chromatography, and clinical assay reagents.
• Industrial Cleaning & Descaling: Effective chelant in specialized cleaning formulations for removing metal oxide scales without corrosive damage.
• Chemical Synthesis & Catalysis: Serves as a ligand in catalytic processes and a buffer in organic synthesis to control reaction pH and metal interference.
• Personal Care & Cosmetics: Functions as a sequestering agent in lotions and creams to improve stability by binding trace metal contaminants.
• Water Treatment: Employed in boiler and cooling water systems to inhibit scale formation caused by calcium and magnesium ions.

Quality Control

Our Glycine, N,n-Bis2-Bis(Carboxymethyl)Aminoethyl-, Pentapotassium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and analytical applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
