Description

n-(2-Hydroxyethyl)Iminodiacetic Acid is a versatile aminopolycarboxylic acid derivative, valued for its strong chelating properties and solubility profile. This compound is crucial for applications requiring the effective sequestration of metal ions in aqueous systems under a wide range of pH conditions. It is primarily needed by manufacturers in the water treatment, detergent formulation, pulp & paper processing, and specialty chemical synthesis industries.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor in boiler and cooling water systems by chelating calcium, magnesium, and other metal ions.
• Detergent & Cleaning Formulations: Serves as a builder and chelating agent to enhance cleaning efficiency by inactivating water hardness ions and stabilizing bleaches.
• Pulp & Paper Industry: Used in bleaching processes to stabilize peroxides and improve brightness by controlling transition metal catalysts.
• Chemical Synthesis: Functions as a key intermediate or ligand in the production of more complex chelating agents, pharmaceuticals, and agrochemicals.
• Textile Processing: Assists in dyeing and finishing processes by complexing metal ions that can interfere with color uniformity and fabric quality.
• Personal Care Products: Incorporated into formulations as a stabilizer and chelant to improve product shelf-life and performance.

Quality Control

Our n-(2-Hydroxyethyl)Iminodiacetic Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and loss on drying are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
