Description

N,n-Bis(Phosphonomethyl)-L-Aspartic Acid is a multifunctional, phosphonated amino acid derivative. This compound matters as a highly effective chelating agent and scale inhibitor, offering superior performance in demanding aqueous systems. It is primarily needed by industries involved in water treatment, oilfield chemicals, and detergent formulations where controlling metal ions and preventing mineral deposits is critical.

Application

• Industrial Water Treatment: Key component in cooling water and boiler water treatment formulations for scale and corrosion inhibition.
• Oilfield Chemicals: Used as a chelating agent in scale squeeze treatments and as an additive in drilling fluids to control calcium and magnesium ions.
• Detergent & Cleaning Agents: Functions as a builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions.
• Pulp & Paper Processing: Acts as a chelant in bleaching processes and a dispersant to prevent scale formation on equipment.
• Textile Auxiliaries: Employed in dyeing and finishing processes to sequester metal ions that can affect color quality.
• Agricultural Chemicals: Serves as a component in certain herbicide and micronutrient fertilizer formulations for improved stability and efficacy.
• Personal Care Products: Potential use as a chelating agent in shampoos and liquid soaps.

Quality Control

Our N,n-Bis(Phosphonomethyl)-L-Aspartic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration or HPLC and identification by FTIR, to ensure it meets defined specifications and is free from significant impurities. Certificates of Analysis (COA) documenting purity, physical characteristics, and other critical parameters 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). 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 degradation.
